Repairing these PCBs was not an option due to the delivery amount. Oxidation is unlikely, as these anomalies were visible right after unpacking them and the humidity card was not suspicious. We have since decided not to use these PCBs as the risks w

I agree with the two other replies. Left alone, it is a defect. If it's just excess adhesive or coating, you can use IPC-7711/7721 'Rework, Modification and Repair of Electronic Assemblies' for guidance on removing. Section 2.3.1 explains how to te

Hello, I am looking for inputs (experiential or opinions) concerning field reliability of high-frequency RF boards that have had a trace or pad repair (or both), any package type. If anyone can comment on this subject, I would appreciate it. We bu

Hi, We should wavesolder a PLCC44 package. The PCB is under the design procedure now and we must specify the best parameters (the orientation (45 or 90 degrees) of the package on the PCB,the number, the positon and the size of the solder thief pads

Does anyone know the current cost to repair a defective solder joint? I seem to recall a number quoted a few years ago of $1.03 per joint with burden of overhead. I've also seen numbers from 50 cents to 50 dollars per joint.

Marc: My experience found reliability IS a function of operator skill and attension to the process. Expecially for some RF assemblies. I worked with an engineer from Rogers to develope a process for reworking Pads for a special material. (I thing
