We've experienced similar problems with film caps, specifically Panasonic's parts that are alledgedly compatible with both reflow and wave soldering. They are identified with either GB or JB p/n suffixes, which become either GX, GC, or JC for the ref

Thanks for your advise Now I don't found Non-wetting defect at TIN COATED 0603 after I had increased peak temp and Time above 183 C. At film caps, I still found Non-wetting in high rate at film chip size 2416. I using PANASONIC's part with identif

We had problems with Panasonic film caps with a previous employer. The first step was to use their recommended pad layouts rather than industry standards for the part sizes. The second much more helpful resolution was to complain like hell to Panaso

No direct experience with this particular issue....but, I do know that measuring capacitance can be tricky. How are you arriving at this conclusion? Are you measuring the caps on the bench before assembly, and then on the boards post assembly? Cap

Soldering electronic components like electrolytic capacitors can be some of the most difficult terms in PCB repair. Electrolytic capacitors, like other components, come in two main formats. 1. Through-hole capacitors have long leads designed to pass

We're not sure what you mean by temperature sensitive components. From an assembly process stand-point, every component we use is temperature sensitive to one level or another. More specifically, some of our products use polyphenylene sulfide (PPS)

We had the same problem years ago when we started using a radial inserter. The inserter would dutyfully insert and clinch the leads. The problem in our case was the component body sealing to the fab, especially on electrolytics caps with a film jac

Yes, I've seen it recently and it's most likely a component problem. A cap is essentially a sandwich comprised of multiple layers. the layers are either wet film or dry film. The end terminals may either be hot soldered or sputtered so there are a

Usually it's the motor start caps blowing on the motors - take one off a failed motor and check the type strapped to the side - our older ones use these: http://hk.element14.com/genteq/27l571/capacitor-polypropylene-pp-film/dp/1735893?ost=27L571&se
