Hi everybody, Is there any criteria as far as No-clean flux residues surrounding solder joints when using selective solder machines? I have a Novastar SPA 400 and use flux NC kester 959. If I decrease the amount of flux, then I experience problems w

Dave, *The machine looks to keep a steady 290c (I can confirm) *This problem is machine/product specific. We have three other Pillarhouses that run the same alloy/flux but only run this one product at this station. *The solder does have a "tail" whil

Thanks for the info mike. How well do these batch cleaners work with densely populated through hole boards that were solder with no clean flux? Is there a problem with water getting trapped under large capacitors? I'm using kester 959t for flux on b

We also have a pillarhouse jade but opted for Kester 959T. The low solids content allows us to use a very small shot of flux thus resulting in low residue on the boards with great solder joints. Solderability is still good but had better results with

We are going to be using a no-clean paste (smt)and no clean wave solder flux on a small pcb we will be doing here soon. As far as the wave process, should i purchase a new fluxer stone for the no-clean. Should I also purchse the recommended thinner o

Two questions on ESD: 1. What is recommended method ( Air ionizer , grounding strip etc. ) for a board prep ? We Kapton Tape for masking pads or not to be soldered areas. or Is there a wet mask recommended for masking boards campatible with NC Sold

Hey guys. I've been manually dunking circuit boards for 8 years now. I too have the excess residue issue to contend with. I'm using a low solids - no clean flux from Kester (959). I have used solvents, thinners, windex and a multititude of cleane

Hello Ashok If you are talking about the thousands of volts that is often generated by either simply unrolling the tape to apply or when it is removed from the board after soldering you don't have a lot of choice since it is an insulator. Ionization
