If you have soldered with HASL finish then the worrying chemistry will be more like NON IONIC. They sit there and attract moisture like mad and any chlorides they hold ionize in the moisture attracted and cause electromigration or SIR issues. They ca

Unfortunately, I don't see any image. If your part will survive 300C then even convection reflow should work. The use of paste and reflow ovens are for when you move to production quantities. It sounds like you could hand solder your prototypes (proo

First, I should state that my company manufacturers batch and inline de-fluxing systems. Because we manufacture both formats, we remain unbiased. In fact, it is in our best interest to recommend inline cleaners since they sell for considerably more

Thanks for your advise Now I don't found Non-wetting defect at TIN COATED 0603 after I had increased peak temp and Time above 183 C. At film caps, I still found Non-wetting in high rate at film chip size 2416. I using PANASONIC's part with identif

Here are some answers to my questions after a good research. I also added more definitions that could help understand this esoteric language used in assembly, specially surrounding fluxes and their use. In blue italics are comments and extracts from

Hi. We are currently using an unconventional method to rework a micro BGA - removing component with hot air, fluxing the area, placing the part with pick and place, then reflowing it in the oven. The reason we are doing it this way and not with a r

Hi, I need the RF 800 Flux Acid titration procedure and also require EPT of the same to add thinner ( RF 800 additive), i.e we are using the flux rf 800 for our wave soldering process having foam fluxer , after 2 hours we are taking sample from the

It depends on the application what will be considered the biggest issue to avoid (production or longterm reliability). Tin Whiskers are bit of an unknown quantity - but a more realistic problem could be dendritic growth / electromigration forming sho

hello, can anyone explain why i get dross like this? flux and alloy i use was not changed. this started to happen a month ago when i took out a large quantity of solder dross out of pot. thank you

Hi, for this kind of issues I will always go with the flux first. Are you using only one type of flux? Is it alcohol based or water based? Do you apply a good quantity? Second I will go with the wave shape and speed, and last will be the temperatur
