Hi John, Our ERSA rework station came with a soldering iron that has a few special tips. We normally do not have a stencil and use tacky flux, so I use the concave tip to prep the pads. This leaves solder on the pads but with a little practice you

Hi BJ, Everyone's favourite answer...it depends! If the volume if large, masking boots will save you both, time and money in the long run. Custom boots are relatively expensive to buy, but they pay themselves over time by savings on masking tape. ma

arent there environmentally friendly solvents (i have seen some from 3M) that can be used in a vapor degreaser. i was also planning to use the vapor degreaser to clean boards prior to conformal coating

Of course there are solvents which are less harmful to the environment than others. The operative phrase is �less harmful�. As a rule, water-based chemistries are �greener� than solvents. There are some solvent blends designed for aqueous-based eq

We are about to use BGAs on our equipment. We clean all products prior to confomally coating them - to keep moisture off the IC legs. Will this be a problem with BGAs. Will we need to get the coating underneath the BGA or will the pitch on the balls

Well how can I correct this? Would baking the board prior to any operations help? Is this an issue I should get the PCB manufacturer involved with, or something that is common and just live with it?

Our front panels (where the controls show) for our assembled amplifiers are anodized and we make sure that it is free from oils or other stains prior packing the whole assembled unit. We just use damp cloth in cleaning and sometimes flux remover for

We have a current problem on our packages after we bake it for 24 hrs prior BGA rework. Flux or white residues found on the connector leads and terminals that cause not contact problems during mating. Could you help us how to clean the fluxes properl

thanks for your reply, actually we bake the PCB assembly prior the rework because the package was exposed for quite some time already. The baking time was 24hrs @ 125 deg.C. We notice that there were flux residues on the connectors after the baking.
