FYI: not all OSP are created equal. I have had expierence, both good and bad w/ OSP boards. To qualify the vendor I would take a bare board and run it thru my oven twice on a reflow profile then flux it with NC flux and run it thru the wave solder fo

Would the lead finish on this part happen to be Paladium? I had a problem similar to this some time ago and we found the lead finish was not tin/lead over copper but paladium over nickel. We had to increase the reflow to 225 deg. C peak temp with t

Hi, I would like to know if someone is using a immersion AG for their board and if this plating modify the property of the solder paste? do I need to make changes on my temperature profile? We want to change from HASL to Immersion AG to mount

Hi mates, since I read about this immersion Ag plated PCB, was wondering if its so damm good, why so few people are using it? and why so long to market its PCBA application-virtues? feedback from bouncing this question around is Ag is prone to corr

Hi mate, think "GSI Lumonics" a Canada based mafg of laser orientated product-machines may be able to help you. we saw their SVS8200/8300(machine model) theory based demo. looks good enough to warrant the time and resources to evaluate their machi

Looking for some direction from you folks in regards to finding water jet (or similar) depanelizers. Currently, we have the pizza cutter style depanelizers (which work fine) however some issues are coming up concering fracturing of ceramic chip cap

I'm sure if it was as simple as that, the AOI technology wouldn't exist. It does however so there must be a need out there for it. Perhaps companies have taken your advice of "save money" to a level that now requires excessive detection controls to b

Hello, As you know for the double side assembly PCBs, we normally first place the bottom side, then place top side after reflow soldering of bottom side. are there any other considerations for the sequence of reflow soldering ( bottoms side first, to
