I created a spray fluxer for our wave solder years ago that is still working well although does consume a lot of flux and is also rather messy. It's cheap and easy though so what the heck, right? I just machined a manifold that will hold four BETE

Hi esoderberg - I was wondering if you had tried altering your soldering profile to try and fully solublize the no clean flux residues and elimate your cleaning dilemma? You can check out my company's website if you want some free reference material

A PCBA contains a couple of parts that are not sealed and can't be water washed. We hand solder these with no-clean after everything else is water washed. The designer says the no-clean residue must be completely removed so that it will not affect

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

We use hot air leveling (HAL) process in pcb production. HAL process is 3 steps. �n 1. step flux. 2. step is HAL. And 3. step is rinsing. As you know there is mustn't any flux after rinsing operation. Our flux chemical is water soluable. But there ar

Hello I am having a problem with the flux in the wave solder, I am using a sonoflux 9000 this machine uses a air knife to spray the flux, it creates a mist that when hits the air knife pulls the mist up to the pallet where the board is, but for som

Grant, Newer lead-free fluxes have 6%-10% solids content - more activator, therefore leave more "visible" residues. Old technology tin-lead fluxes got down to as low as around the 4%-6% range (I'm going off memory, so me might be wrong)... You'll

No clean residues can range in appearance from brownish gunk that looks like tree sap (because it is in some instances) to almost no residue at all. Is this product exposed to a wave soldering process or SMT? I would guess it's a wave process if th

We have been doing BGA's for years now, and I would suggest updating your profile and place a thermal couple on the BGA, keep in mind the bigger the part the more heat it will need, We stencil print all of BGA's from simple bga's to complex ones, you
