Hi Jeff, Your board supplier could be correct in this way. The board could have had just a hair left of copper on the circuit, which would hold up under the electrical test process, but once you powered it up, then there was enough juice to burn th

BoardHouse, Thanks for the reply. The board supplier did cover the cost of the bare boards. Five years ago I saw a different part pass ET only to fail at final assembly test as well. One engineer called it "acid trap" on the inner layers where the

I have tried just about everything avalible for BGA inspection on the market. We use X-ray which is great, even through we have a 5-d machine, I use my 2-d unit most often. We also have the expensive scope that lets you look completely through under

Other areas you can focus 1) Find out alternative chemical and solder materials for lower cost. 2) Set high power consumption machine (such as Oven and wave) to idle mode when not running to cut electrical consumption. 3) Reduce the used of N2 gas.

I'm thinking that your soldering irons are not up to the task. take a tip temperature measurement of the iron prior to and during soldering process. With high temp solder alloys you need an iron that provides continuous temperature at the tip. Doing

I'm also looking for tips for SMT hand soldering with Sn05Pb93.5Ag1.5. Our technician is quite good with standard SMT hand soldering, but hasn't worked with HMP solder. Some specific questions: - If the iron tip is hot enough (consistently), can we

Hi, We are currently having issues with hand soldering High melting point solder wire. Can anyone give a few tips. We are Preheating boards to 120 deg C and using soldering irons @ 410 deg C. The quality is ok but the ts taking 20-30 seconds to c
