When learning CTP hot press binding process, I encountered two problems. I would like to learn from you: M $?. D} 6 t! X) e1? 9 L1: The main reason for the efficiency of preloading alignment of OGS (single-layer multi-point structure) is that the golden finger on OGS can not see clearly.
* A: T "K0 L" X4 a $W%_ 5 l.
\) Q(preloading: OGS is below, FPC is above, CCD is above, ACF glue is generally pasted on OGS) 1 a (^ 0 ~ "I2 J8 I 'D1 S & E)2: After the ACF adhesive is pasted to the binding position of sensor, FPC gold finger can not be seen clearly on CCD display during preloading.

the results show that the FPC gold finger can not be seen clearly when the ACF adhesive is pasted to the binding position of sensor*{) ~. O4: C '[& z6a3 # {affects the preloading efficiency.

1. Is the preloading machine specially for OGS? 2. If it is an OGS machine, adjust the focal length of the CCD display.
2When changing CCD.
to high-power, change to blue photoelectric.
the following factors will affect the image blur: "B1 v.] $? & O7 o #? 7 P-V / G + H1. The focal length is not right and needs to be adjusted;'F.
t ({* {& E? 9 ` 2. Since CCD camera systems are equipped with coaxial light source, the light emitted by the light source will reflect on the surface of the golden finger and return along the normal line for CCD to receive. Therefore, it is necessary to ensure that the light path of the camera system is perpendicular to the plane of the golden finger and must not be tilted. If tilted, the light reflected to the CCD will not be enough;4 J! B7?, m #] #? 0 U6 P4} A3. The light source used is not strong enough or the improper light source is selected, high power white light or blue light source can be used.

'n1 Z (z) R1 \'m6 BIf it's convenient for you to tell me which brand of CCD is used for the special equipment you see. I'd be more grateful if you have photos.
thank you very much7 o7 x0 W8 m) C! H4 m; j.
