1. Stress: also the most headache.
2This LCD module is originally quite expensive. The boss is definitely not willing to give too much to the test machine. If he doesn't try it, he doesn't know how the effect is. Is there a standard for this force? Which master is doing, please let me know, thank you! ---------------------Each kind of equipment is different, the pressure is different $n $H!

Bubble problem: if it's a G + G paste, it doesn't matter if the force is a little higher, but the module is different. If the force is too large, it's afraid of crushing the LCD screen. If the force is too small, there will be many bubbles, or there will be dead bubbles. After the bubble is removed, whether it will rebound or not will rebound --- bubbles mainly depend on the OCA, the flatness of the equipment platform, and the rebound also depends on the OCA material.
if the force is too large, there will be many bubbles, or there will be dead bubbles! A & O) C2 Z (Z & T +] 6 F "Q & T. V!" ^ 3 V6 Q6 D; R3, the flatness of LCD module: because there is a border.

select a better vacuum fitting equipment.
make special fixture according to the product, and the vacuum fitting equipment is compressed by air bag, It doesn't matter if the strength is a little bit stronger. At least it won't cause the module to be crushed. And then there will be bubbles. If you use OCA to fit, there will be bubbles, so choosing a better defoamer is the key. I hope the above can help you.
