| All Y'll | | How do you clean components that must be added to an assembled board after water wash? | | BACKGROUND | | Our basic process goes like this: | | 1 Print paste with OA flux, place, reflow, wash | 2 Repeat 1 | 3 Insert PTH, OA flux

| Hi all, | | I thought I'd use this forum to ask a couple general questions on fluxes for manual operations: | First - Is it OK to use a wave soldering type flux (specifically OA)? Thinking about activation temperatures and the ramp rate of the wav

Agree with what has been said so far. Check with your end customer and make sure the white haze appearance of the board will be acceptable. You will never get the board to look like it did before you started. It may be clean but it won't look like t

Sorry, but I don't know this brand. Anyway pay attention, because if the chemistry is resin based, is difficult to clean and the residuals may be hygroscopic. So, I only can suggest you to read the data sheet and follow the instructions by the solder

Hi, we have ERSA flow selective machine. We are using 420s-lf No-Clean flux (lead free process). It is water based. Before that we used for about 2 years in JS-EU-31 (KOKI) (alcohol based). It did excellent job (we moved to water based flux just bec

Q1. Is it enough to use only water while cleaning or is it necessary to use any additional chemistries and/or saponifiers as well? A1. It depends on: * Flux residues that you're cleaning * Standoff of the components * Cleaning technology [we've neve

Does anyone know what the requirements are for the maintenance and frequency of cleaning wave solder carriers? as I am in process of writing a procedure amd don't really know what to include in it. All the carriers use no clean chemistry. Thanks in

We agree with Mark. Why do you want to schlep your boards to another part of the plant, clean them, and schlep them back to the process? Not value added that schlepping stuff.

Hi Ramon, The obvious answer you might expect to here from me is that you could probably reduce your misprint problem if you had a good stencil cleaning process. Please see my response to the question by MarkT on �Cleaning Materials� because it i

Kris: I can appreciate your hesitance. Done correctly with proper planting and fore thought, the change to no-clean affects every part of your operations operations from purchasing to receiving and on down the line. Two things: 1 Following with y
