Considering all the constraints you are faced with, I would try changing the apatures for that part on the stencil. It seems as though a no-clean "homeplate" appature would put less paste on the board. Less paste means less flux, and it might be en

The answer for us at my previous employer was water soluble flux. Wash the board, no residue. If you're not set up to wash (needing a washer, DI water source, waste treatment, ventilation, etc.) it can be expensive and space consuming. Do some resea

Hi, I could like to find out what are the things need to look out if I'm doing a new SMT solder paste ( water soluble & no-clean ) evaluation. And also flux ( spray type ) for wave-solder ( water soluble & no-clean ). Appreciate for all the input..

Too many hands in the bucket, unless the owner is one of the engineers. Typically flux is not rated or classified by "feel". What are you soldering? Wires? Components to PCB? What is your cleaning capability or requirement? Aqueous? No-Clean? Ul

Questions are: * What are the soldermasks used by your three board suppliers? * What tests have you run to assess the compatibility between these three soldermasks and your flux?

Casimir: Let me expand on something that I said in my response to your thread on ionic testing. Generally, no-clean people don�t use ROSE testing as part of their process control, because the ROSE test is essentially washing your board in DI/IPA �

Graham STOP!!! You can not be totally serious. A five year old cost model counts bean, and beans are beans. I have to know more about the calculation. If this bores some of your gear-heads, click on "return." � Help me with the terms: - "Ops cos

We're currently using no-clean flux (SR-12) in a no-clean manual soldering process. The brownish flux residue impedes direct visual inspection of the solder joints. Therefore, we're forced to clean the residue off. (1) Is there testing we can do

J-STD-001C, 7.2.1 Flux Application says words to the effect of: When an external flux is used in conjunction with flux cored solders, the fluxes shall be compatible. Regardless of whether these are or not flux cored solders, this begs the question:

Hi I don't see in your note any particular reasons why you couldn't. If it solders well and passes what ever specifications you are using than everything is OK. If your repair faces some soldering or rework challenges where a more agressive flux is
