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

You can use straight forward Tin/Copper but it flows very poorly so solderability is an issue. Dosing with Phos improves this but need to stay on top of it. We have supplied some 3.8%Ag alloys for flow they work well but you get a small 'chill point'

The critical operations where cross contamination can occur is the paste printer, the touch up station and the hand soldering station. Hand insertion should not be a problem if the parts are kitted or issued with proper control. If possible I would

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

Dear Patrick, Unfortunately we do not know what exactly the failure as our customer refuse to reveal to us. From visual inspection the solder joints are smooth and shiny as per IPC-A-610 requirements. The component supplier (IR) commended that they

We are currently in release 1.4 and 1.5 of the majority of our courses, partly because we do fix minor errors that do crop up, and release maintenance updates. I infer from your comment that you take exception to one or more of the test questions in

The 3000 hours is correct. It was a VERY fast ROI! Back to the discussions on the earlier threads, some of this information is correct. If you exceed the design limitations for keep out requirements and your board tolerances vary, you can have twe

Hey all! As background, I recently purchased a full SMT line for my company. We have a DEK 265, an assembleon opal xii, and a Heller 1500. Currently our jobs are leaded, and the heller is working perfectly. An upcoming job that we are potentially g

I agree re; "always will be some assemblies that must be repaired". This is unlikely to lessen in the near term with an imminent move toward Lead-free. We are currently working with Cookson, PACE, and BEST developing a course in lead-free rework wh

If you do not have any luck finding a west coast lab, but need services I am sure we can help. The only problem is we are on the east coast. Many moons ago empf was on the west coast (China Lake) but moved eastward. We are in Philadelphia, PA. (ski
