Forgive the non-SMT question. That's why I hate through hole boards. Has anyone ever used Bareco wax on pressfit connectors, and how do you produce a consistent process for its application? Any drawbacks? Background: We have found a design issue with

That was our first course of action, and we cannot get solder to adhere to the pins using an iron with solder roll, or by dipping them in a solder pot. We have added flux to the leads as well. At the moment our only success has been with the use of

Hello Sean, We are currently using a Pin in Paste process to mount some through hole relays. This particular board has 72 relays per. We have cut the stencil to overprint the hole. By putting a small amount of solder in the hole to flux the lead, th

Again, I would like to refer to the tape dimensions and their deviations. In an 8 mm tape the distance from the sprocket holes to the tape pocket is 3.5 mm +/- 0.05 mm. This tolerance is easy to achieve, because in the manufacturing process of the ta

We are starting to see a large increase in the use of through board gold plated connectors that require hand soldering with the limitation of .o6" encroachment up the pin. What is the best way to accomplish this? we currently scrap about 5-10% of t

In general, they certainly can be touched-up. I don't know of a CM yet that doesn't use a touch up step of some description. However, you'll want to be looking at the process to try and determine what is causing the pin holes and blow holes, and tr

We are a medium sized PCB assy. house manufacturing about 2000 motherboards a day. There is a major problem we are facing at the wave soldering stage, i.e. warpage of the PCB. As soon as the PCB touches the wave it warps severely from the centre to

Just a thought: if nothing else makes sense, you might want to watch the action of the edge-hold chains of the reflow oven, are they moving smoothly and uniformly around the drive gears and idlers? I've actually seen the situation where the chains we
