You are going to struggle with that sort of connector - the only pin headers that seem to have widespread sucess are the dual inline ones with bent over j leads that sit on the board. They come with a plastic hat that allows vacuum pick up. However

Are you setting up double side PCB that has the tall components on the bottom that being push up by the support pins... ??? Or because your vacuum is leak and not holding the board at the same spot every time you are loading the board.... Board warp

Depending on the system you can program in a loop where if the board fails a contact to cycle the vacuum once or twice. it wears on the pins a little faster since you cycle 2 times (maybe more) per board but it could help increase the FPY. I know Gen

we have fuji's cp-iv-3 machine made in 1993.we are facing problem everytime when we change the jobs(for example we change from pcbA to pcbB to pcbA)even though program is same. There are some mechanical adjustments like conveyor adjusted according to

You mean it's not OK to celebrate Notre Dame loosing its ninth straight bowl game since 1995? * Notre Dame has lost the last 16 games against teams with top 10 rankings. * Fighting Irish haven't beaten a team of real consequence in the last two seaso

Seriously, OSP?, change the board finish, you are the OEM, correct? You have the power! Also, as another poster mentioned, high force applied at ICT ( possibily to cut through the OSP goop ?!? ) could be warping the board enough to crack the joints.

Things to consider... Print alignment - Use off contact Printing and verify board supports - In machine ensure part profile is correct with correct nozzle and thickness - Use support pins in machine to limit placement bounce - Limit input from produc

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

I'm not familiar with the mechanics of a Fuji but when we were learning to run our chipshooter, we did not correctly assign board thickness in the program. This caused the board support pins to warp the board up just enough to push nozzles to a par
