Hi, we do Sn plated I/O pinning insertion into Ni/Au thru' holes. no problems here so far, as we cater for the "interference" (fit-allowances) of the I/O pin into the thru' diameter, via improved PCB thru' hole designs. before this cater/considerati

Sal: Hey that customer standing around staring at you sound like fun, yeh right!!! Wolfgang makes good sense, but, in addition, I�d like to drill-down on board fabrication (har har har) a little bit (har har har) more. You say the holes are the cor

Currently we have started seeing an issue around a scuzzy connector.The problem being that during insertion of this connnector a couple of pins refused to be inserted and as a result fold over, this folding of the pin is causing the pin itself to fra

Hello We have recently started to work with press fit but we are finding problems to reach the specifications in terms of hole deformation and whiskers. Do someone have experience in key process parameters and PCB design specifications (PCB harness,

Oh yeah, I've seen this before! Generally, if the hole sizes are correct (including plating), and the PEMs are within spec, we've found that this is most commonly caused by insufficient support of the PCB during insertion. If you can eliminate supp

The connectors are well within thier specification,and are also checked for misaligned and damaged pins , as regards the cross-section results, all holes are correctly aligned and are well spaced within their tolerance of +/-0.005 (a couple of isolat

Sal: If it�s not the PCB, what about the connector itself ? Is it from a different production lot with some unregularities ( dimensions, tolerances, pin alignment, material weakness)? How about handling, storage, shipping causes ? Could it be a tooli

i don't know of any "handy dandy" but something I use is tape width minus 4mm for the max component size that can be fit into tape widths of up to 32mm. 32mm and larger have holes on both sides which would then be tape width minus 7mm. I have never
