Ladies and Gentlemen, As a newly appointed DFM/CE "guru" here, one of my responsibilities has become repair (of course). As I have some knowledge of BGA repair/rework using semi-automated equipment, it naturally follows I would hav tremendous insigh

Hi, Bill, Lead-free solder and paste manufacturers will be a great resource for you during the transition; they've tested their products extensively, and their application groups have been able to help me through the biggest changes. There are a fe

Thanks for the advice. We have only done one PCB > with HMP solder and did not use preheating, but > I've been wondering if it would have been helpful > since we had some trouble getting the solder to > flow. If you have any more specific advice

We've got this hard-to-Wave-solder board where all of the SMD's are on a ground plane - in fact the entire bottom-side is a ground plane. Our designers have incorporated thermal relief on some of the pads, but for reasons unknown to us, they don't h

Hello to everyone. I am not a technician of any sort, so I don't even know the name of the part I'm going to ask you about. Basically I learned this stuff by myself. I bought me a Playstation One and tried to install a chip on it. Here's a pic of the

I�m not sure but it looks like the �mini-chip thingie� is a filter cap if so it should not stop the playstation from working, may not work like you like but should do something. Did you use any static protection? If not you may have fried one or all

Steve, I'm using 5 Sn/1.5 Ag/93.5 Pb Solder wire with a melting point of 300 deg. C to connect my thermocouples on smd components for thermal profiling. I'm using a soldering iron with an adjustable temp. to be able to melt my solder wire. Temp is ab

Hi Jason I think Wolfgang has this one nailed. If it's the same four pins every time and nothing changes this, even rotating the board 90 degrees, then you're probably going to find something like a ground plane connected to them. I don't think sol

Solder 'follows' heat. 1. Preheating is a great idea, use a baking oven to get the whole assembly up to temperature, use the preheaters in your wave solder machine (without wave) to preheat the assemblies ... 2. Or use the biggest soldering iron
