‘DESKTOP’ SYSTEM

Operating principle The system is a Desk-top system and is built up on a chassis with integrated controls. The machine operator is responsible for the manual positioning of the product components. The alignment of the product components is done in a fixture (by means of a micrometer screw, one or more dowel pins and/or a camera-monitor system (optional). After having positioned the product components, the system can be operated by means of the start button(s). The joining cycle will be executed now. After having executed the joining cycle, the joined product can be taken out of the fixture. The joining cycle is defined as follows: The thermode is moved down pneumatically (Z-axis) and heated until the preset temperature has been reached. The joining operation is carried out with a constant thermode temperature. When the preset time has passed, the thermode will be cooled down by forced air cooling until the lift off temperature has been reached. The thermode will move upwards again. The Uniflow scedule is activated and the system is ready for the next joining cycle. The principle of the Desktop system is based on joining the several product components by means of a controlled movement of the thermode, thus creating a known, force at a preset temperature and time.

Noise level The sound level has been measured according to the Machine Directive requirements. The A-weighted equivalent continues sound pressure has been measured on the working place during normal operating conditions. The noise level has been measured on a distance one metre from the machine and at a height of 1,60 m above the reference plane. The measured A-weighted equivalent continuous sound pressure level (LAeq) will not exceed 70 dB(A).

Requirements for the surroundings Generally the equipment requires no special foundation; a level concrete table is sufficient. During production, the machine and the near surroundings must be illuminated well.

6 SYSTEM OPTIONS PER CATALOG 6.1 Uni-Base systems with no movement DT-150-PH: SH500, Uniflow With the model 150, parts need to be positioned directly beneath the hot-bar (thermode). It is equipped with an anodised aluminum base plate that has a hole – pattern drilled and tapped into it. This hole pattern accepts a fixture base plate. The fixture base plate has dimensions of 160 x 160 mm. It is mounted with bolts, and references on dowel pins.

6.2 Uni-Slide systems with manual front-rear slide DT-250-PH: SH500, Uniflow, 2-position manual slide DT-260-PH: SH500, Uniflow, 3-position manual slide The slide makes loading and (un-) loading the parts easy. When parts need to be aligned, a slide is normally used to load and align the parts in the front position. The rear position is then used to bond the parts. By having two positions for these two actions, operator safety and ergonomics is increased. At the same time ideal camera positioning can be guaranteed.



The model 250 offers two positions, one for loading / unloading / alignment, the second one for the bonding process.



The model 260 offers three positions. One positions is still for loading, unloading and alignment. The other two are two bonding positions.

A thumb - operated lever unlocks the slide to go to the next position. When the right position is reached, the slide automatically locks into place. This ensures an accurate

and fast positioning.

For safety reasons, a sensor checks if the slide is in the correct position for the bonding process. Only then the process cycle can be started with the two - hand control. In case there are two bonding positions, two separate sensors are mounted. With these two sensors, independent process settings for both bonding positions can be automatically recalled.

6.3 Uni-Slide systems with left-right slide DT-270-PH: SH500, Uniflow, 2-position manual slide The left/right slide makes it possible to load and unload parts in one position while the bonding process is taking place in the other position. This increases (almost doubles) the output of the slide system. When the right position is reached, the slide automatically locks into place. This ensures an accurate and fast positioning. For safety reasons, a sensor checks if the slide is in the correct position for the bonding process. Only then the process cycle can be started with the two - hand control. Two separate sensors are mounted. With these two sensors, independent process settings for both bonding positions can be automatically recalled.

The automatic slide makes loading and (un-) loading the parts easy. When parts need to be aligned, a slide is normally used to load and align the parts in the front position. The rear position is then used to bond the parts. By having two positions for these two actions, operator safety and ergonomics is increased. At the same time ideal camera positioning can be guaranteed. The model 350 offers two positions, one for loading / unloading / alignment, the second one for the bonding process. The model 360 offers three positions. One positions is still for loading, unloading and alignment. The other two are two bonding positions. The system will automatically move from the first to the second bonding position. Compared to a manual operated system this saves operator time. For safety reasons, a sensor checks if the slide is in the correct position for the bonding process. Only then the process cycle will be started. In case there are two bonding positions, two separate sensors are mounted. With these two sensors, independent process settings for both bonding positions can be automatically recalled. 6.5 Uni-Turn systems with manual rotary DT-440-PH: SH500, Uniflow, manual rotary

The manual rotary table makes loading and (un-) loading the parts easy. When parts need to be aligned, a rotary table is normally used to load and align the parts in the

front position. The rear position is then used to bond the parts. By having two positions for these two actions, operator safety and ergonomics is increased. At the same time ideal camera positioning can be guaranteed. The rotary table has two positions. For safety reasons, a sensor checks if the table is in the correct position for the bonding process. Only then the process cycle will be started. The position repeatability is accurate within hundredths of a millimetre. This high accuracy level is obtained though the use of a high qualitative guiding. Both bonding positions have a fine adjustment possibility to position the hot-bar (thermode) exactly above the bonding area. The rotary table is supported in the bonding position. This ensures optimum co-planarity and offers the best bonding quality. The turntable moves from one to the other position by manual rotation. The table is locked in each bonding position in an accurate way. 6.6 Uni-Turn systems with automatic rotary DT-450-PH: SH500, Uniflow, PLC controlled pneumatic rotary

The automatic rotary table makes loading and (un-) loading the parts easy. When parts need to be aligned, a rotary table is normally used to load and align the parts in the front position.

500 N head Adjustment of the parallelism between fixture and thermode The adjustment of the paralellity consists of two adjustments: 1. Coarse adjustment > 250 micron 2. Fine adjustment < 250 micron

NOTE: Both adjustments are completely different and therefore they should always be carried out in the order of first the Coarse and then the Fine adjustment.

Coarse adjustment: Course adjustment is carried out by moving the base plate of the head. This means, that with this adjustment is possible to move the base plate in three axis: 1. Horizontally e.g. Head position in X-axis 2. Vertically e.g. Head position in Z-axis; re-calibration of the force might be necessary 3. Rotation e.g. Head adjustment in X-Z axis (parallel adjustment) 1. Mark the old position on the support if possible. 2. Adjust the side support plates into the middle of their adjustment limits (see Fine adjustment) 3. Loosen the four screws that clamps the base plate onto the head support. 4. Use a steel bar and spacers to get the base plate at the correct distance from the working table. (Since the table top at the factory is used as a reference, you may also use this as a reference.) 5. Carefully tighten the fixing screws one by one repeatedly, every time using more force until the base plate is firmly tightened to the support column (Use X selection of the screws to tighten them). 6. Check if the X position is still correct; if not repeat step 3 to 6 until satisfied. 7. Coarse positioning is done; now proceed with Fine adjustment.

Fine adjustment: Fine adjustment is done by moving one of the side plates very carefully by means of adjustment screws 1. Remove cap from the pneumatic head. 2. Remove air pressure from the system. 3. Select only the left side plate and use only this one during the adjustment procedure! 4. Fasten firmly the not used right side plate to the frame. 5. Press by hand the pneumatic shaft until thermode nearly reaches the fixture. 6. Put on each side of the product support (of the fixture) a strip of pressure paper 67W0003 / 67W0023. 7. Move the head by hand down until it presses on the paper strips. 8. Determine on which side the paper strip clamps by pulling them one by one. • When on the left side the paper clamps, move left plate Up by loosening first the top screw; then fasten the bottom screw. • When on the right side the paper clamps, move left plate Down by loosening first the bottom screw; then fasten the top screw. • Check the clamp force of the paper strips on both sides. If they are equal go to the next step. CAUTION: The adjustment screws should always clamp the side plate in position before checking the clamp force! 9. Remove the paper strips and replace them with a piece of pressure sensitive paper. 10. Make a print on the pressure sensitive paper and check for equal coloration of the print. 11. If one side of the print is darker then he other side move the side plate: • At the darkest position Up by loosening first the top screw; then fasten the bottom screw • At the lightest Down by loosening first the bottom screw; then fasten the top screw • Adjust until the coloration is equal. Every time use a new piece of pressure sensitive paper • If the coloration is equal, the parallelity of thermode and support will be less then 2 micron.

Force adjustment of the 80N head: It is important to understand the movements in the head before you made an attempt to adjust the work force of the thermode/head. The system consists of three parts: The cylinder piston and the movable blocks A and B. Block A and B will follow eachothers movements as long as they run freely. Block A can only be stopped by the mechanical stop adjuster. To block B the thermode is mounted and can only be stopped by the thermode which hits your product. As soon block B reaches a stop (e.g. your product surface) and block A is still moving, the spring is depressed (therfore building up force)until the mechanical stop adjuster blocks the movement. If we reduce the distance between block A and block B by means of the locknuts [upper and lower locknuts force adjustment] of the [force pre-set shaft] we pre-tention the spring thus giving a pre-force setting. So if we start the cycle now, the thermode moves down until it hits the product; the force on the product is equal to the pre-set force of the spring. force spring : no tention

Now the firing switch gets important. The function of the firing switch is to start the heating process. However, when it starts, the force on the product should be stable, e.g. NO movements should take place. The switch has a very small operating area around 1 mm (0.04 inch) and therefore we let block B go down just 1mm more and then we block the movement by the [mechanical stop adjuster]. Firing switch in normal position

This will activate the switch, stop all movements and the heating process starts. Since all build up force is related to movements, it is extremely important that; if you measure the force for calibration, the tophight of calibration device is at exact the same hightlevel as (the fixture hight + pcb thickness+foil thickness) to avoid missreadings and / or wrong adjustments.

7.3 Thermo-Plane thermode The thermode is heated by means of a controlled PWM (phase with modulated) output of a Uniflow power source. The maximum stroke of the thermode in vertical direction is 25 mm. Position repeatability of the thermode in X-Y direction is within hundredths of a millimetre.

Figure 18 : QCB & Thermode

7.4 Quick Connect Block The connection of the Thermo-Plane Thermode of the bonding head is achieved by using a Quick Connect Block (QCB), which is mounted to the bottom of the bonding head. The special shaft of the screws guarantees the position reproducibility of the thermode. Standard size options of a QCB to support the corresponding thermodes: • QCB 50 up to 50 mm thermode length • QCB 100 up to 100 mm thermode length • QCB 150 100 up to 150 mm thermode length NOTE: Use a QCB and thermode as a set!

7.6 Interposer Module

WARNING: Installation, technical maintenance, repair and (de)mounting Of the Interposer may only be done by technical qualified persons, unless specified otherwise. NOTE: The Interposer is NOT needed for soldering!

Interposer (Interlayer) can be used between the hot-bar (thermode) and the products. This is common practice for heats-seal and ACF Bonding. The Interposer is normally an aluminum oxide filled silicon rubber tape, 5 mm wide, 0.45 mm thick and 10 meter long. The module consists of two reels (spools). One spool holds a full spool of Interposer, the other one is used for winding the used interposer. The module connects to each standard quick connect block. The Interposer is pulled loose from the hot-bar to prevent it being squashed to one side by the repeated squashing. The tension on the Interposer is being kept constant by a spring-operated lever. The interposer has several functions: 1. It protects the hot-bar (thermode) against glass splinters. 2. On the PCB side it forces the adhesive in between the tracks, making a stronger mechanical connection from the flex to the PCB. 3. The Interposer is flexible, and events out small flatness imperfections that can be present in the parts.

There are two options of the Interposer module: Manual: The interposer material needs to be manually transported by the operator.

To refresh the tape proceed as follows: 1. Loosen the two locking screws (2) in front of the Interposer mounting blocks. 2. Lead the tape through the reels (left to right) until an unused piece of tape is positioned underneath the thermode (6). 3. Fasten the two locking screws in front of the interposer mounting blocks.

NOTE: The Interposer must be refreshed regularly. Periodically, for example twice a day, lead the tape through the reels over a distance, equal to the thermode width.

Automatic: After a programmable number of cycles, electrical motors automatically transport a programmable length of interposer. This length is normally equal or slightly more then the length of the hot-bar.

7.7 Kapton Feeder Module

NOTE: The Kapton Feeder is optional for soldering only!

A Kapton Interposer can be used to prevent pollution between the hot-bar (thermode) and the products. The Kapton has 25 microns thickness, 5 mm width and is supplied on reels holding 200 meters. The module consists of two reels (spools). One spool holds a full reel of Kapton, the other one is used for winding the used Kapton After each soldering cycle, electrical motors automatically transport a programmable length of Kapton. This length is normally equal or slightly more then the length of the hot-bar. The module connects to each standard quick connect block. The Kapton is pulled loose from the hot-bar to enable transportation. The tension on the Kapton is being kept constant by a spring-operated lever.
