Your supplier�s approach to managing process change is TOTALLY UNACCEPTABLE!!!! Now, let me get the froth back in my mouth. How in the world do we know if the residues on these "no-clean" boards are compatible with your product? J-STD-001C, para 4

saturation occurs at ppm levels. Remember, IPA is extremely flammable and its bulk use makes the plant liable to all sorts of quite repressive safety rules/regulations and so on. Ignoring these rules exposes the owner to fines and possible plant cl

Hello Jeff, If you have components on your board be careful of how low the frequency is that you will be applying to your board. Ultrasonics are great for cleaning stencils and bare boards at around 40kHz. These frequencies (and Lower)may however

New pcba supplier sent us first article pcbas (SMT, Wave & hand solder operations) that failed our testing due to no-clean flux residues found under ICs and around passive capacitors. Second lot came in and had 100% pass yield, but we still see a cl

Yes this is absolutely true. No-clean flux residue has various affects on the functionality of circuitry especially high impedance circuits. It also affects solderability, and reliability. No-clean flux will always leave a detectable residue. Mos

i am working with the noclean process and getting white residues on the bottomside of the board probably due to the wave soldering flux.i am using a no-clean solder paste and a noclean wave solder flux.The boards passed the accelerated temperature a

GJ: If your supplier uses a conformal coating that "must be applied to a clean surface," then you are using the wrong supplier and no amount of twiddling with your N2 levels will change this. NC fluxes are inherently "dirty" and nothing aside of cle
