I�m looking for some type of fastener to secure identification tags to boards. The method would be inserting through a tooling hole on the brd .25� npt. We had been using nylon fasteners much like those used in the garment industry. However I am look

Jeff, what I generally use as a rule of thumb on multi-row connectors was a strip on the trailing side of the connector as it flows through the wave. The strip was always the same width as the diameter of your through-hole. The distance of the stri

Greetings, Could somebody recommend a good parts counter that can handle taped SMT and thru-hole components? I'm looking at some counters made by APS and some made by Grip, but I'd like some feedback about these products from people who use them. A

Hi Dave, I read the same article as you. But that method leaves solder balls in via holes or traces of it remains on the boards. I am using ultrasonic with solvent for cleaning misprint boards. Apprarently, they have adverse affect to the en

I'm just shooting ideas here, but maybe a via hole in the middle of the solder pad would drain the excess solder by capillary force? Or using a tin plated PCB and printing flux only, then place and reflow. depending on the thickness of the tin plati

I have a supplier that utilizes a soft beam solder process for through hole components. We are experiencing bridging and cold joints on components with narrow pitch between pins. They are dragging the solder over these pins as well. I have asked f

I wouldn't recommend a metal squeegee, because if you can't wipe the step-etched area completely clean (that's the problem with metal) you'll have problems with the definition of the fine-pitch (it may stick in the holes). Best is a 70 Shore polyuret

Printing: use rigid carrier plate to hold and support your flexible PCB. tooling holes in PCB to position on the plate, two-sided tape to hold PCB in place. Oven: same carrier plate, use capton tape or clamps to hold PCB in place. I believe some in

We haven't run a profile yet....probably because we're a-feared to. We can't do topside preheating here to any degree because we use an aluminum plate for aligning hundreds of top side through-hole components (pots, switches, buttons, LEDs) that te
