Differential pressure transmitter is a kind of pressure measuring instrument widely used in all kinds of chemical industry. Working principle of differential pressure transmitter is as follows. The differential pressure from the two-sided pressure pipes acts directly on the two-sided isolation diaphragm of the differential pressure transmitter sensor, and is transmitted to the measuring element through the sealing fluid in the diaphragm. The measuring element converts the measured differential pressure signal into the corresponding electrical signal and transmits it to the converter. After amplification and other processing, it becomes the standard electrical signal and then is output.

Does anyone encounter components sticky problems? I think it should be ESD problem in cover tape.

yes, contamination could cause sticky also.

Ken is not of this World! His equipment and "Programming Team" is perfect. The rest of the world uses "sticky" boards when programming. "ALL" the big guys...Panasonic, Fuji...etc suggest using the "sticky" method beofre running any production boar

Hello, We have the same problem as you. We have used Acetone to remove sticky successful. Thank you

wash->ssd top->wash->sticky flux bottom side->place smt components->reflow->wash->sticky flux top side->place topside smt components->reflow->wash) ssd is basically the process of applying solder paste to the pcb with a stencil and the solder reflowe

Sounds like a rosin flux. Is it sticky as well? Russ

we use a stencil and aply paste to the BGA have used sticky flux but prefer pasting the BGA

Are the parts kept in a humidity controlled environment ? Perhaps a little humidity is making the silicon "sticky".

Whatever, we process the cover tape to troubleshoot the provlem.
