do not forget,ROHS Directive does not allow other chemical substances (ie. PBB, PBDE,....) that could be in PCBs, so the PCB must be ROHS compliant and not only Pb Free. That means be carefully when marking PCB or PBAs. Regards..........GS

yeah, I wonder what will be the next? "Do not touch with same fingers PCBs with SnPb and Lead free PCBs as some molecules of lead may stick to your fingers" :D

I rarely use blk fiducials. But when I do, they are always programmed after the fids. It's the fids that sets your general alignment of the panel. I only use blk fidus for thin pcbs (30 mil) that tend to warp when on the conveyor.

Hi, We have a customer that want us to produce a single sided 0.4 x 100 x 50 mm size RoHS pcba approx 1000 of them. The board only contains three 2.54mm pitch Non P.I.P, SMT-connectors. We have never produced such a thin pcb:s before. We are thinkin

SWAG, The reason that our suppliers are focusing on moisture is that vapor pressue increases exponentially with temperature. So the higher temp processing of RoHS boards causes a significant increase of vapor pressure, which may cause delamination

We do the following things: 1.) RoHS PCB:s is marked with a code. This is to identify that the PCB:s itself are RoHS compliant. 2.) If it is a true RoHS PCBA; we put a printed label with a green "texture" on the PCBA. 3.) If it is a mixed PB free/PB;

yes you can use lead-free components and/or lead-free solder paste on Sn/Pb PCBs. You do get reliable joints. as already mentioned, it doesn't meet the WEEE and RoHS requirement. Indy
