There is no current standard for the amount of flux that should be applied to a board. Current standards focus on what the result of a process should be, not how the process should be performed. So, the standard tells you that you need a procedure de

When using a foam fluxer: 1. Bubble size is important. What stones are you using? Ever clean them? Too large a bubble will NOT help your situation. (I forget bubble size range....check with your fluxer mfgr.) 2. Thinner will help in capilary m

Hello, We are buying a Vitronics-Soltec wave solder machine with a spray fluxer to replace our old Econopak that has a foam fluxer. Currently we thin our flux (Kester 951) in the foam fluxer per Kester PS-20 and PS-22 test kits with kester 110 thinn

Are you making sure that the all the alcohol in the stone is pretty much gone before you put it in the tank? If the stone is dripping with alcohol when you put it in the tank, you could be affecting the specific gravity of the flux so much that it ca

Hi Adam, We had a reverse of the previous - if we didn't have our smartwave running at at least 750 RPM behind the main wave, the pressure dropped & gave us inconsistant soldering. Otherwise... 1) are the components tarnished at all, or stored in

Anyone have experience wave soldering rigid flex assemblies? I've just picked up a new job from a customer; it's a rebuild for the company, but new to me. The customer had previously taken their business elsewhere due to delamination problems with

I have found that preheating the solder pallets prior to use helps cut down on the solder balling. Also, we do not cool the pallets between passes and we use a spray fluxer because a hot pallet will knock down the head on a foam fluxer. We use WS f

I am about to embark on an effort to evaluate 3 different solder material suppliers and their recommended materials for our assembly process, in an effort to find the best supplier/material. We do mixed technology, with NOCLEAN chemistry so I will b

Beware the foam fluxer. I had a problem with cracked caps that just about drove me off the deep end. I discovered that my foam fluxer air knife was not turned on resulting in excessive flux. The excessive flux (VOC free) was not properly dried off
