I can't believe there is a topic for discussion. Find a way and measure lead contamination(if any)and prove them wrong. This is getting out of control. Having all the billions of gasoline and diesel engines pumping dirt in the air, together with the

I am assuming that your application is Automotive. The logic here is that the product has got to at least run for 8 years or more. The prebake removes any moisture that may creep into the product during the wait time. A little moisture combined with

From what I understand when ROHS was first implemented the EU planned on testing products. But the EU economy would have shut down if all the physically non-compliant products were pulled. And now it is more showing due diligence. Remember it is poli

Hi All, I'm using 8 zone reflow for ROHS 0.2mm Thick PCB soldering, but Micro BGA shows voids more than 25%. Is there anybody can suggest for better solder profile. paste- aim m8, SAC 305, T4, Soaking (150-200) - tried 90s, 60s, 45s; TAL (>217)-

Hi Everyone, Can you please suggest how to achieve 100% solder coverage of two Thermal pads on BRD1260C component..??? Surface finish is OSP Copper & Solder Paste is Sn/Pb 63/37. Component is Gullwing leads type. PCB having 1.60 mm Thickness.Peak Tem

You likely have raised belly pads. If possible, do a step-up on the thermal pads to compensate for the additional height of the component in this area. Some reduction/adjustment of the gullwing pads may be necessary, so be prepared for a few iterat

If it was ROHS, I would say that the pads are definitely dissolved away. And it sounds like that is the case here. Your best bet is if it is class 2 and the barrels are at least 50% then push for them to be accepted. If you are trying for more barr

No experience with low temp solders for PIHR but we do use standard lead free 245-255 peak profiles on high temp connectors frequently. Honestly the added cost of the high temp connector pays for itself in labor. I almost always use oversized apertu
