We are using Mulicore MF101 flux and a Vitronics selective soldering machine on a lead-fee assembly and are having trouble with nozzles blocking even when the nozzle aperture is increased. Has anyone come across this problem before using fluxes with

Hello all, Has anyone used Kester 2331-ZX water soluble flux on selective soldering and expirienced a white film after soldering. I have seen this on and off for a few weeks now and believe it is a chemical reaction with the solder mask or improperly

Hello, We have recently bought ZipaTec select 250, we are having problems with offsets. Somehow the offset of fluxer, wave and preheat dont match one another or the program we create. The previous owners are of no help. The main question i have

Hello everybody, We are in the process of implementing NC process on the wave solder. We have a Sonotek XL fluxing system. Any ideas out there? Solder used: SN100C Flux options so far: 264-5 flux, 270WR VOC-free 9both from AIM solder) The flux ch

You may want to try raising your pre-heater if you have one. I would also suggest trying different fluxes that may be a little more active so you can use less. What type of fluxer are you using? Selective solder flux residue is a gray area. This i

Armando: We're guessing that the white residue is on the laminate also. We believe that the residue has something to do with your low residue flux and water. It could be: * Water contamination in the flux. * Poor selection of preheat temperature that

Hi everybody, Is there any criteria as far as No-clean flux residues surrounding solder joints when using selective solder machines? I have a Novastar SPA 400 and use flux NC kester 959. If I decrease the amount of flux, then I experience problems w

Your supplier�s approach to managing process change is TOTALLY UNACCEPTABLE!!!! Now, let me get the froth back in my mouth. How in the world do we know if the residues on these "no-clean" boards are compatible with your product? J-STD-001C, para 4

Glenn, There are both very good VOC-Free fluxes as well as alcohol based fluxes out there. This should be your primary focus if you are so lucky as to have to opportunity to actually select a flux! The use of nitrogen will benefit any no-clean pro

My company is just getting into the flip chip packaging arena. We are putting in a prototype/small volume wire bond PBGA line. We have some questions with regard to choosing solder balls and cleaning of flux. 1) Is there a formula for the shrink
