We have a board with an LQFP-176 with 0.5mm pitch. We regularly have to rework these due to unsoldered pins, which is due to pins that are slightly bent upward. We believe that we are receiving them this way, but it may also be due to handling on o

hi, I am looking for some guidelines which can tell me when gullwing and finepitch leads are too damamged to repair. Copper gets hard when bent and the electrical resistance increases. When a finepitch component gets dropped a lot of pins need staig

We currently have a job that uses press fit solderless pins. The pins are custom and only supplied in bulk packaging. I am looking for a machine that can orient the pins and present them to my insertion machine. Of course i need the pin to be present

My recollection is that there is a carrier clip locator that positions (centers) the clip in front of the CTA. Has the adjustment on that been confirmed as well? (Edited because some of it's coming back to me!): I think there is a diamond shaped pin

Hi, I am considering to use pressfit D-Sub and DIN connectors on a backplane. The IPC guideline does just cover pin protrusion for soldered pins, which have to be flush with the board as a minimum acceptable design. Yet, if the backplane may be thic

I think that as long as the compliant portion of the pin is completely in the board, pin protrusion should not make any difference. I have seen some large Aerospace companies internal specifications and the two requirements seem to be that the compli

Check that your boards haven't been over plated. Too much plating in the hole can slump to the underside of the board during reflow. If you are then press fitting on the underside of the board you can have problems with hole diameter. If the hole is

First thing I'd use is IPC-A-610C, �4.8.2 Connector Pins - Press-Fit Pins. Does it work in your case?

Hi, Does anybody know where I could get a cheap but efficient press for press fit connectors (200pins and up)? Pneumatic or Hand lever Mario
