I'm looking for test labs in Taiwan that are capable of performing ionic contamination testing on small to medium sized SMT boards. I'm interested in both ion chromatography and ROSE test methodologies. Is anyone aware of any labs performing contami

We manufacture both bulk and localized ionic contamination testers. My answer is from the perspective of the cleanliness testing method. The issue with all bulk ionic contamination testers (Ionagraph, Omegameter, Zero-Ion), is that they test the en

For more than you want to know about static and dynamic testers, read EMPF report RR000013, "An In-Depth Look at Ionic Cleanliness Testing". Request it from http://www.empf.org/index.html#

Asoe, The systems you are describing are Resistivity of Solvent Extract (ROSE) Testers. These systems are available using one of two technologies, Static or Dynamic. Both systems use a calibrated test solution comprised of IPA and DI water. The t

Can any pls enlighten me what is the purpose of using DI water during washing of PCBA. If the board is not wash using DI water , what will happe? What is the range of resitivity reading should be. Rdgs...

Hi, we are looking for a contamination tester in this stage however it looks there is 2 ways of removing residuce from PWB: static and dynamic. Both introduce their advantage to me and cause me further confusing.I am not anyone here will have tried

Mario: Your ask a very broad question and give no background information. Generally, the amount and type of residues present on a printed circuit board at the very beginning of a SMT line depends on the exposure of the board up to that point. For

There are a lot of lead testers out there. Just google it. I personally don't think you will find anything wrong, but for the pleasure of your customers buy one and prove it. I would also check the lead on the squeegees of your stencil printers and t

Edmund: Responding to your questions: 1 What is purpose of using DI water to wash a PCBA? Compared to tap water, DI water is less likely to leave: � Metal cations on sensitive components. � Salts of Ca, Mg, and other stuff on metals on the assemb
