Duno. What's the diameter of: * Finished connector lead * Finished through hole We reckon: Lead size plus ~0.25mm [0.010"] is normal.

Paul: If your customer "resolders suspected IC lead(s), problem goes away" - It's not an 'black pad' issue. You need to improve the way you solder this product.

Looking for a thru hole part that you can solder a wire or leaded part to. I remember using them in the past - but the name escapes me. It had a forked end that the lead would fit into. Any help appreciated.

Hi All, I was wondering if any of you have any ideas on what is the optimum angle for the conveyor to pass over the waves on a leaded wave machine ? Any input would be greatly appriciated. Regards Darron

Lead spacing is probably an issue here. It would be better if your lead pattern was staggered, like the RJ-45 to the right. It appears there may not be enough flux on this part of the pcb.

Is there any electronic digital devices or other easiest ways to use to determine any unsoldered pins/leads besides some other normal inspections like using microscopes.

I cannot see it's a gull wing lead, but also there's no solder under the lead except the side surface.

The leads on the FPC are pre-tinned on both sides with SAC305. The receiving leads are AU. We do not experience any wetting issues that would suggest oxidation.

The leads on the FPC are pre-tinned on both sides with SAC305. The receiving leads are AU. We coat all surfaces with Kester 979 no-clean flux dispensed via pen prior to initiating the hotbar cycle.
