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

Others make good points. Consider "TP-1115 - Selection & Implementation Strategy for A Low-Residue No-Clean Process" as a starting point. Remember that in-bound components and boards can be loaded with unNC res that can turn the best implemented

We use an evaporator, so that we only have a sludge of flux residue and solder metal to dispose of via the hazmat handling service. We also route stencil washer waste water into it. We use a 30 gallon drum and have it hauled off maybe twice a year,

Need some input here..... The fear is that the if we use water soluble flux at the repair operation, that the no-clean encapsulation will capture some of the organic material as it cools down and goes to its original state. The organic material wil

The answer for us at my previous employer was water soluble flux. Wash the board, no residue. If you're not set up to wash (needing a washer, DI water source, waste treatment, ventilation, etc.) it can be expensive and space consuming. Do some resea

I would recommend some sort of saponifier that has been tested and is known to remove the no clean flux residues that you're trying to remove.

Dear Ing, Have you analyzed why some RF device aren't operational after washing? An assumption is that failures are related to the ultrasonic energy applied. Other possibilities are for poor rinsing, poor drying, inadequate washing on those failed

Brian: SMTnet has a "Terms & Definitions" section in the "Library." OA Flux. Flux, Organic Acid. A water soluble flux. Good luck Dave F

Clean everything to do with the print process during the switch adequately and you shouldn't have an issue.

jng123, Process-wise using one solder paste type is preferred regardless of paste type. If you want clean both paste types in one cleaning machine your manufacturer might have, this potentially could lead to white residue issue due to chemical reac
