Beyond just the cosmetic dewets reliability is very flux/coating dependent. Don't forget about any touchup or hand soldered parts after wave as well.

We currently use Kapton tape to cover a display. The only real purpose for this tape is to cosmetically protect it thoughout the process. The display gets hand soldered and washed, so the idea of the tape being high temperture isn't a factor. Becaus

Can anybody gimme some input on the problem I faced currently on 0402 Chip Resistor. At pre-reflow the component are placed nicely but at post reflow, we found the Resistor stands sideway ( both termination, the pad and componant are in contact, fun

No-clean is definitely a cheaper process. It will eliminte cleaning. Some issues associated with no-clean are: -- the flux stain left behind on the PCB will create a cosmetic issue. You may want to seek advice from your customers. -- next, the flux

I am having cleaning problems when processing PCB's which have TAIYO solder mask on them. After processing, hand soldering and cleaning, a sticky residue is remains, resulting in a cosmetically poor finish with tide marks etc. Other soldermasks do no

Hi all Does any one know problem with solder joint call crystallised joints. I have noticed that sometimes on our PCB when i look at the joints for example chips, LCCC, there are areas not smooth solder (very often in the center of the solder joint)

Hello, Heres my take. If the ends that are touching are connected by trace, and IPC-610 is satisfied, and the connection does not make a Parallel circuit where a series circuit is required, then I would treat it as a process indicator. That is, unle

Yikes!! In-line cleaning, to clean cosmetic and benign residues (from a NO-CLEAN) flux... You sure you can't switch fluxes? Another variable with residues is the solder mask. Depending on mask type (glossy, matte, semi-gloss, or semi-matte), will

Hi George, Depending on your product, wave soldering twice is not all that bad. Residues will be higher, but should only be cosmetic unless your product is sensitive to ionic contamination. You can set-up an alternate profile on your wave for 're-

Hallo Joanne, I had employed by producer of Ecofrec 303. We make many tests of corrosion and conductive test in our company. All results of this tests was OK . Vast majority correspond mil standarts. When I ask my labor assistent in BRY, white residu
