Hello, Unfortunately I have lost my hard copy of "Soldering in electronics" by R. J. Klein Wassink. Is it possible to purchase electronic copy of the book on the net? Having googled a couple of hours, I have found nothing. Any input is highly appr

Appreciate your suggestion. NSMD pads are used for this design, the anomalies we found are 1. the trace running between pads has a lesser solder mask height compared the other area of the pads. 2. the NSMD pads doesnot have a trench close to pad e

We sometimes have a misprint and we would never re-print on a board with paste on it already because it will surely get paste all over the bottom of your stencil and could smear between traces. If we do mispront we have to clean the paste off the boa

A friend in the contract coating business said: "... ask why the wire is [teflon] coated in the first place, as only the solder joints should be coated in this situation as the flexing/bending of the wires will cause the coating to crack and flake of

An assembly with this improperly solder joints will have functional issues. We have encountered this many times with memory modules failures,RMA units. Reflow always solved the problem (in our many cases). Dwelling time may be the key to solve this.

Good day, Having recieved new batch of PCBs with OSP surface finish, I have noticed that some polygons not covered by solder mask and solder paste become darker after second reflow cycle compared to PCBs not being sent to reflow. I wonder whether i

Is anybody using Vicor VI Chips (SMT version)? We are using a number of these on some of our boards and are having inaccurate placement and insufficient solder issues (8 mil step stencil still not enough). If you are placing these devices: 1. Which

Just about to set up a lead free solder pot exchange system for my Electrovert. Wondering if anyone has had success using say large ball bearings or materials which will sit inertly in the bottom to occupy space and reduce the alloy required without
