Dendritic growth is always a result of three combined factors: Conductive/corrosive residues Electrical current Moisture A wave solder process normally applies a higher volume of flux than a printed process. Flux however is not the only source. F

We have utilized the ERSA Scope for over one year. Our experience is that it is an excellent product in evaluation of problematic assemblies. It takes a little bit of time getting dialed in on the equipment but once you have it mastered it can see

I am in the mid-Atlantic US. I need to solder PCB's to a large copper heatsink. Does anyone know of local (or not so local) ECM's with vapor phase capabilities? How about induction? Thanks!

Test Resistance to ECM shall be 65C +- 2C @ 88.5% +- 3.5% All SIR Measurements shall not exceed 100 MOhm. I am not sure of voltage.

Even 93% humidity, it will has no condensed water film inside or on PCB, it will have no ECM or CAF, for such consistent 40℃ temperature.

yes, the void should not expose the conductor or bridge the conductor, the coating there should be thick as IPC required but you need minimize the voids and bubbles. ALso for those small chips, a void or bubble on it means possible ECM, normlly shou

Does look like delam, if its that bad and the board looks like its HASL finish or Silver, it could also be porous absorbing the chemistries of HASL or Nitric from the Silver which will greatly encourage ECM or poor SIR figures or just simply eat the
