The tooling fixture has tooling pins to accomidate your PCBs. Typical PCB tooling holes are 0.125" dia. non-plated thru holes and 0.250"x0.250" from the edge of the PCB. Check out this link to EMC Global Technologies. They mfg. tooling fixtures for U

Hi everyone, I am looking for a reliable company (preferrably on the west coast) that can make Wave Solder and Press-Fit fixtures for our back-plane division. I need a reliable source that can take our data and produce quality fixtures in a 5-7 day

Are you positive that the solder is sticking to the bottom of the fixture OR is it pushing the wave down so far that the solder is "squirting" out from underneath the pallet. This happens when deep/thick pallets are run at the same wave height as a n

John, We tape (usually high temp tape) flex to a fixture (usually 0.090" piece of bare FR4). We make an outline on the fixture to get a rough location then use fiducials on the flex for alignment. Print, place, reflow, cool, remove flex. When the

Which fixture material is LEAST LIKELY to warp? Please advise. We used ta have a Wave Optimizer but the corpulent engineer before me broke it before he left the company. Anywho, my next project is to design a wave fixture pallet which will work

dedicated fixture works best if the board is very much populated. But if the parts to be inserted are less than 300components, adjustable fixtures may be used. But the secret of good insertion is a precisely measured tooling pin to prevent the boards

The dedicated fixture never really wears-out. You may need to change tooling pins and hold-down tabs, but it will still be accurate when we are all long gone. The adjustable fixtures seem to wear-out. Depending on usage and care it may go from 3 y

I think Patrick is on the right track. Try running the fixture 180deg out from typical, if possible, and see if the problem goes away or moves to another fuse clip. I've also noticed some wave fixtures can create air pockets that won't allow proper

A good fixture is the key here. The first side should be easier than te second(if double sided). In both cases I will try to level the top of the board with the top of the fixture. Try to lock with pins comming from the fixture to the PCB holes. This
