SMT process sensor surface high temperature polyimide film

CMOS high temperature resistant protective film detailed description (specifications can be customized according to requirements) The CMOS high-temperature resistant (adsorbent) protective film is attached to the sensor surface of the photosensitive chip. After the reflow temperature is 280 degrees, the high temperature resistant protective film is torn off after 10 minutes. Under a magnifying glass with a magnification of 100, the sensor surface has no residual glue and
