Generally QC is a different deptpartment than touch-up people. Most touch-up people are just general operators, so to keep their job they always see the solder joint as "not enough". Q.C. people are generally a bit better, but know they may be call

Hi, Yes, I would hate to resort to cleaning, but the product must be clean. We have been using palettes to keep most of the flux off the PCB, but there is still residue around the connectors. Does anyone suggest a good no clean flux to use with le

We use EFD pneumatic dispensers. Several are second hand from our favorite online auction site. I just checked on there and there are 3 units currently less than $50. Have the bean counters where you work get you one. Tell them your hand hurts from u

I think the 1st option would be the best. I have found that a touch up person WILL TOUCH UP SOMETHING, regardless of the electrical needs of the board. This leads to a lot of unnecessary rework of joints. I would hope QC is tracking the defects and t

GS I am not a lawyer and the European directive has a lot of grey areas. But if you look at 1.2 in the link I send you it states that when an appliance can still function when the electrical current is off this type of equipment is not covered by di
