Hi Cory, As a manufacturer of aqueous cleaning systems, my advise is somewhat biased, however I believe it to be accurate. We have hundreds of customers who have implemented no-clean programs. The programs have been successful when measuring the r

Pros are no need to clean after reflow. No need to buy a cleaner or worry about "wet" parts afterwards when you're trying to test your unit. Cons are that most leave a bit of a residue behind. It's harmless but may drive your bed-of-nails tester a

First, I don�t understand why your board fabricator can�t do a good job plugging your vias. Additionally, when you consider that they forgot to plug the first batch of boards, it makes me wonder if they are desirable as a supplier. Generally, we us

I've a query. I have one new Customer whom insisted us to use RMA paste on their product. The problem is, on some of their products they use via hole as the test point in where all the PCB finished are ENTEK and as usual I have to print solder paste

Murad, I have just completed a switch over in our facility to no-clean. We used Alpha 609 and 857 paste and wave flux respectively. We currently use Alpha UP78 paste, NR330 wave flux, NR205 liquid flux for touchup and cleanline 7000 wire solder as

Hi Larry, Picture a old lady with a set of knitting needles with leads attached to them, pressing the needles into different points of the PCB (pads, test points or component leads) and measuring resistance, inductance, waveforms etc between these p
