Thanks SuMoTe, I've already tried fluxing various boards (new clean ones and older ones) without turning the waves on and with different temperature setups (within the suggested params from Alpha) in the preheat zone. The results were in many cases

There are competitors to REL solder alloys from AIM. Tin-Copper-Nickel-Bismuth alloys (Nihon Superior) are an alternative option which do very well in thermal cycle testing. The reflow profiles required are similar to SAC305 profiles. You may als

We are currently producing a project that brings a TQFP64. But some boards do not solder the component well with its ideal fillet, some are well soldered when they come out of the reflow oven, but some are not. Can the pins be sulphated? How can we c

Hi, I'm currently in the process of evaluating a number of 3D AOI machines such as Koh Young Zenith Alpha HS+, CyberOptics SQ3000, Mirtec MV-6 Omni, Parmi Xceed L and Aleader ALD8720S. Does anyone have any thoughts on these machines as to which is b

I ask for advice on starting wave soldering machine. The soldering machine is not new. Are there guidelines for properly loading solder into a bath and more. I also ask you to recommend an alloy. What do you think about Alpha Sn Plus 07 or SN100C(Sn

Scott is right, Alpha' 2110 is a good saponifier (be careful though as it can dull your leads). Saponifiers in general are better if used in an aggressive spray-in-air system. Low agitation immersion systems (heated baths or refurbished vapor degre

We have been using Alpha Tetra/DEK Vector for the last 3 years. Prior to that we were using mesh on frame. We do about 15 job changes a day and our main runners are loaded about 4 times per week. In the three years we have been using the system we h
