I have a question for the Wave/selective Solder experts. We use a solder bath to Tin the legs of Transformers that are made in house. We use a Marselli BK4. It uses 50/50 solder. The question is, at what temp is best for this solder. Anyone use this

You didn�t tell us about your solder, wave temperature profile, or the distribution of the problem. So, let�s assume the solder is near eutectic and the problem is wide spread. Wolfgang makes good points. So, let's talk a different tact. When we

Hello Steve, Yes, there are differences in the various alloys and I have described briefly below these differences: SN100- a common name for 100% tin that is used to increase the tin content in 63/37. SN100C-Name for Tin/Copper/Nickel/Germanium all

Q: I thought you said that the parts that weren't wetting in reflow were the parts with epoxy. A: Yes you're correct. Q: The question I have is do they wet in wave solder, and if they do, why does it matter what happens to them in ref

We're inclined to buy Russ's stuff about peel from the wave. Look here, but shield your eyes first: [ http://www.thepdfshop.co.uk/ppm/defects/Wave/asp/50.asp ] [A respectful bow to BW for the pix] Could you tell us more about: * Board direction thro

Hi, We are currently using WonderMask PX Peelable Solder Mask # 2222 for the wave rework process, but we are having a lot of trash in the pot. I understand that it is because the solder mask resists the pot temperature (500F) but not the rework tim

| Hi Folks, | This is my first surface mount board, so I asked our assembly house for some tips. They said only passives on the bottom side-preferably no smaller than 0805, 0603 only if I have to. I would think that an SOT-23 would be OK on the botto

| A rash of new products here at my company have designs with multi-pin connectors 90 out-of-phase (orientation)wiht respect to wave direction, which has lead to massive bridging (shorts) problems.... | | Does anyone still use the 45 Degree Pallet

Hi mates, I encounter a problem on PCB after going thru the LeadFree Solder Wave. It shows so much dirt or dross on the PCB surface. I have attached the picture for more details. I have tried to scope out suspected solder dross and oxidedized solde
