I have seen smt chip varistors with Pd/Ag teminations that had poor wetting in terms of good fillet in LF (sac305) soldering. We found that the solder tended to be attracted to the plating on the part and off the actual pad (silver Immersion). This c

Poor reading skills......that being said, with good resolution (3 megapixel and up) digital cameras so readily available, and cheap, why not use real pictures? After all, a picture's worth a thousand words... In the '90s, I used to translate CAD/Ge

While it's possible, we don't think that soldering a wire of this low of an AWG to a board is a good idea. We're concerned that mechanical vibration and heating / cooling will stress the solder connection to the point of failure during routine table

What volume of boards are you putting through. 1Kg per hour does sound very high but then again it does depend on volume Using an antioxidant is a must with Lead Free some alloys have additions in them to start with but those drop out with use so th

My factory produces Printed Circuits Boards.Today, my customer says they encounter problem with solder ability issue. Some of the boards have difficulties during SMT solder flow. Could not stick to the pads and the components fell off. Those boards

DANGER WILL ROBINSON ! DANGER ! If your operators are not real careful the OEM support pins can get under the table frame and bend it. I have seen this happen more times than I would like to discuss. CP's must have the following: 1. Proper part hei

Yep, many of us have seen this firsthand. I had a customer who fouled up a job, then "found" a deal on some (10) very expensive Xylinx parts, and badly needed these parts to complete the job. Everything looked good afterwards, but nothing worked. X

I agree with dlm. We have been using Hakko irons for our lesd free soldering for about 6 months now. They work great and the tips are relatively inexpensive - $9 to $15, plus they last a very long time compared to our previous brand that we used. The
