| Can anyone give me the virtues of SMT package castellations vs. no castellations with particular reference to the ruggedness and reliability of the solder joints? Any references or studies that you can point me to? Also, although I'm in favor of

Hi, I have a customer who's electronic assemblies produce RF. He is insisting upon aqueuos cleaning. We switched to a no clean solder years ago and no longer have an aqueous system. Is aqueous cleaning necessary to eliminate 'cross talk' of the s

I got an inquiry from one of our electronics labs with regards to their soldering processes. They use eutectic (63% Sn, 37% Pb) solder. For liquid flux they are currently using Kester 186, which is an old-school, full rosin (RMA and ROL1) flux that c

I have a customer that is having a flux residue problem after wave soldering. Flux is roaring through the board to the top side and leaving a residue. This is only happening on the flat stamped leads. The round leads are fine. They are using Supe

I don't know the name of the flux. but is a no-clean solder paste.

Dear All, In order to understand the soldering technologies in SMT, I'd like to understand why some cards are soldered and then cleaned, or only soldered whitout water cleaning nor "ultra sound" wavelength. I mean that I wonder why we use toxic flu

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

Get the ionic specs from your flux manufacturer, and show it to the designer. No-clean flux/solder is supposed to be low to minimal in ionic contamination, which allow the whole no-clean thing. If he needs further proof, you can have the board io

I believe that NORDSON now recommends AIM NC277. Nordson bought out ACE-protech.
