Hi , We are using water wash solder paste to solder the SMT LED's manufactured by Chicago Miniature lamp (CMD93-21 & 22)and Kingbright. Achieving the solder fillet , wetting has no issue but we observe high fallout at the functional testing. If we do

Hi, We have a SMT production like, however we have very little experience with through hole assembly. We design everything to be completly SMT based, however connectors are the only part of our product that still requires through hole assembly. Cur

Stan- One of our buildings (not our SMT line or components) Has Great Aircondition but can not regulate the humidity. The building is cool but Wet (No need to lick envelopes as they are already stuck together) from humidity. We went out and found th

Marc, There are many types of nylon used in the connector industry and some are designed to be used in high temperature (225-250C) oven reflow applications. These high temp nylons are usually types 4/6 and 6T. It sounds like you are either using a

They take the solder in a dip and look solderability test but when in normal reflow process we got some pins that do not get wet and the appearance is as follows: -Pillow effect on the toe(no front fillet is formed) -There is a sheet of flux between

Toe fillets are not required per IPC. Toe fillets could be used as a process indicator, if you desire; I would not. Gull wing leads are typically cut off on the ends when manufactured; this exposes the non-plated material in the lead, typically coppe

I have a product that has earthing/positioning holes, as they are to be used for earthing purposes they need to be free from conformal coating. This pcb is double sided. I have used spot/peelable mask to protect these holes. However when the conforma

I am having problems with one certain board that is gold immersion. I know it is not oven problems or part problems because it is various parts that are moving during reflow. Also I have not had problems with any other boards going through the same
