Solder flux

Suppliers list the contents of their products in a MSDS. Libraries of these sheets are listed online. Look up the product you're using there. A safety data sheet, material safety data sheet, or product safety data sheet is a document that lists info

What is the issue?

It's a BGA component. Missing ball is not possible because we have enabled the vision in pick and place. Solder paste is OM353 type 5 Possibilities of Flux dry before reflow seems valid but I saw the board data it was completed on time like other

Screenprinting Adhesives

We use steel stencils. The adhesive manufacturer can give recommendations for squeegee type, material, pressure, etc. A lot of the tech data sheets include this information.

All, Get the material data sheets, lot numbers of ink, supplier's process flow, bare boards with ink lot applied ( qty 20), Contact the ink supplier and perform a 3company DOE.

FR4 or CEM3

Electronics Forum | Fri Jun 04 01:13:31 EDT 2010 | boardhouse

Hi fotis, Big difference between Cem3 & FR4 is that FR4 the glass is woven and Cem3 is sheet glass non-woven. for Multi layer product, i would not consider Cem3 due to increase chance of de-lam due to lack of weave for strength. Cem1 and Cem3 are

1B73LOC Conformal Coating

I don't think THEY (Humiseal) know how their material cures. I have a data sheet from them for 1B73, and it says 24 hours at room temperature or 30 min. @ 170�F. We use our in-line oven mainly to dry the material and make it tack-free. You would

Re: AR vs. UR

| I am looking into replacing another business division's Acrylic coating process with our Urethane coating process. Unfortunately, MIL-I-46068 doesn't differentiate AR/UR's performance, and the MFR data sheets don't match up at all (they each spec

No clean and 100 Mbps Fast Ethernet Transceiver

Electronics Forum | Tue Sep 30 20:55:14 EDT 2008 | davef

Residues from different no-clean fluxes produce different levels of variation in RF circuits. Some no-clean fluxes work fine. Following this, a no-clean flux can produce different levels of variation in RF circuits depending on the process setup.

Re: Conformal Coating that doesn't require fancy equipment...

Electronics Forum | Thu Jun 10 21:09:17 EDT 1999 | Samuel F.

Humiseal probably won't work as most of them are solvent based or require pretty high temp cures. MicroCoat technologies manufacturers UV cure epoxy conformal coating materials that have been used to coat just about anythin (except the green fog) Cal

Solder Wire Expiry Dates

Electronics Forum | Wed Aug 26 10:48:30 EDT 2009 | grahamcooper22

Some print expiry date on reels and some specify a shelf life on data sheets. Two main reasons are that the flux in the wire is a mix of chemicals and over time in storage these can react so soldering performance can be changed. Although I have to sa
