Hi! I am Syed from Hitachi located in Malaysia.It seems that the discussion about OSP is very much related to the dillema that I am facing in my company.I am the Senior Executive for the SMT Department at Hitachi.Currently we are facing some issues w

Dear Members, Sorry,I might have not made myself clear on this issue and creating some confusion.Actually the problem faced is during the DIP Soldering process whereby one of the connector(IDE Pin) solder is cracked and lifted from the pattern.Visual

Over the past several months we have experienced intermittent problems with wave solder voids on PCBs coated with OSP. We suspect variation in the OSP application process, or oxidation of the surface due to insufficient or degraded OSP. Is there a me

What are the handling requirments for PCB's coated with OSP? Also do most solder paste work the same with OSP or do I need to use a certain paste type?

use a solder join temperature of 200/210� whatever the pcb used (tin lead coated or osp or gold fash). 2nd ==> to adapt the temerature to the pcb used: - Reflow (200-210�) for tin lead coated pcb's (in this case we have just to reflow the solder

Since you�re asking the question about proper handling of OSP board, there may still be time to talk you out of using that material. * Cleaning of mis-printed board could cause non-wetting problems. This tends to remove a fraction of OSP coating. 0.3

You're correct. We prefer to probe solder, rather than copper, because the solder absorbs the impact of the probe better than copper and so, helps preserve the life of the probe. Beyond that, OSP has a limited "shelf life". If the OSP is not coate

Is it just certain locations on the board, or is it random, does it occur on every board, does this happen on any other products you have been running? If this occurs only on the 1 board and in random locations I wouldn�t say its your wave setup. I

We expect to see a copper shadow along the edge of pads when soldering boards with organic solderability protection [OSP]. IPC-A-610 has defined this as acceptable for years. During early reflow stages, the flux in paste dissolves the OSP where ther

| Okay, here's a stupid question. What exactly is HASL and OSP? We are going to delve into this technology where I work and I want to utilize the wealth of knowledge here to make life easier. Specifically, what are the differences, the advantages, di
