This sounds like information bantied-about by the fine folk at CSL [Contamination Studies Laboratories in Kokomo, IN]. If so, this includes the sum of the halides from the following sources: * Fabricated board * Components * Processing of the assemb

Kelvin, You can find the Standard acceptable levels and testing procedures from IPC. Here's a little advice from the fellas' over at PCFAB: As a guideline, we recommend that for assemblies processed with low-solids flux technology and that are not cl

No, none of us can tell you what is the acceptable level of halide content or contamination in flux residue. The level of harmful residues on your product helps determine the reliability of your product. We know nothing of your product, its custome

We always talk about the halide free fluxes and solder pastes. Is there anyone tell me what is the industrial acceptable level of halide content or contamination in flux residue? All comment are welcome !!! Kelvin

According to J-STD-004 "Requirements for Soldering Fluxes", fluxes are classified by their chemical composition, activity level and halide content. In this scheme, each flux type is identified by a 4-character designator, where: * First two character

Hi, Here we take profile for every changeover. And we compare it with our profile.For the oven performance. We daily take a minimum of 3 profile for one oven. We have High mix low volume production. We are using ORH1 ( organic flux with halid cont

No-clean solder paste is definately a trend for tomorrow. However, there are several points you need to consider before you shift from WS to no-clean: 1. Component quality - No-clean solder paste generally (not essentially) get a lower avtivity than

First, don�t get distracted by �OA� and �NC� formulations. This is nomenclature. We want to discuss the issue of �activity�. J-STD-004 "Requirements for Soldering Fluxes" classifies fluxes by their chemical composition, activity level and halide c

Hi, We're using solder paste opposed to solder wire for hand soldering certain components. We are also using high temperature soldering irons with 450deg C tips as we are soldering onto aluminium (IMS) PCBs. The quantity of tips which we go through
