Although rather expensive, you have to realize they had to go through extensive testing to prove their product safe. This probably cost them extensively. So once the formula has been deemed safe, they just pass this cost onto the consumer. Not to

Richard, With respect to the Resistivity of Solvent Extract (ROSE) test, the test solution is exceptionally aggressive. With the Zero-Ion for example, the test solution�s resistivity is 150 M-Ohms. Additionally, because test solution is made up of

Hi Richard My experience with R.O.S.E. testers has been positive with regard to detecting ionic contamination (even exceptionally low levels). As previously mentioned, a good R.O.S.E tester will be able to detect minuet levels of ionic contaminatio

Good day and thanks for your comments Mike, What did I understood from your notes� 1) ROSE test (�extracting solution�) is probably good enough (with good equipment) to penetrate the space under my micro BGA. 2) I should test 2 parallel batches of

Dear sir, I have a problem to find the new chemical solution instead IPA(isopropyl alcohol) to eliminate contamination on the test pin socket board made from copper that plate with nickle and gold. And after the often testing IC process, the co

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

I have used all of test and inspection techniques available out there: AOI, AXI, Flying Probe, ICT, and FCT. The reality is that they all have a place in manufacturing based on the type and complexity of product you bild, the industry it is intended
