That's a good question. On some of the assemblies that our engineers test, appear to have been reworked in these suspect locations. I have requested rework data from our CM by providing them with assembly and serial numbers. Their data shows that th

Maintain DI water to 18 Meg Ohms resistivity. You can go down as low as 2 Meg ohms, in a pinch, but I would caution on what type of board you are running if trying to clean on 2 Meg ohm. Anything that is running an RF or high frequency circuit could

Hi Pete, Wow, I figured you'd have tons of answers to this one. Anyway, call the vendor of the adhesive you are using and see if they have a cleaner for their adhesive. Most do now. Just make sure the SMT pads and vias do not have any adhesive on

Hello Russ, I believe that the dullness in color of the solder joint is related to the gold finish on the pads. I have had done alot of thru hole soldering of gold pins as well as SMT on gold finish and have seen the condition that you are talking a

Working DFM SMT issues with respect to a client's artwork together with a heavily modified solder stencil, I was able to reduce 0402 tombstoning from 80% across the board to 3%. I winged the aperture reductions, but are there any "rules" or guidelin

Folk's, I'm just tying up some loose end's on my Master's Thesis on solderballing @ wave soldering and the effect the topography of the mask / PCB has on it. I was wanting to do a straw poll on you guy's as to the type of resist's you are using Glos

I guess I wasn't too specific. We currently use 1,1,1 for spot cleaning and minimal rework of PCBs. If there is a lot of rework on a PCB we will use water soluble flux and wash it. This may turn out to be our only alternative, but I hate washing a
