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

J-STD-001 guideline of 1000 lm/m^2 [93 fc] seems high, but it is the minimum level of illumination that operators and inspectors should have to perform their tasks. IESNA LPD Architectural Recommendations Type of Facility||General Area percent / fc

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

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

Pump up the Halides.

We are evaluating a low halide Water soldering flux (Aim WS716). Has anyone had good/bad experience with it? Our operator has mentioned strong and irrating smell, even when standing a foot away from the conveyor entry/exit. The fluxer is embedded w

Glycerine on a PCB is very bad news as it is Hygroscopic and can attract moisture to the Circuit. Alot of this used to be used in HASL Fluxes and is a no go for Circuits that are not going to be washed. They too could dissolve the natural Halides fro

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

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

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
