Don't waste your money on T&R feeders for large parts. I used to have an old TP9 and we ran tons of products with vibe tubes and odd shaped parts. Used to cut our own tubes for parts and jimmy-rig parts like crazy to make them all fit on the machine

| What allowances are people using out there for components off-pad, we currently use 50% of lead width without breaking trace/component clearances but we have a customer demanding 25% allowance ? | IPC states: 50% off pad for class 1 and 2 25% off

Dear all We have since few weeks problems with BGA solder joint integrity on ENIG finish. Under relatively very flexible of the FR4, the joint breaks between ball and PWB. When we take off the BGA for analysis, some of the pads seem very flat, totaly

Thank you ChrisW. I agree completely. The decision to idle the temperature or turn the wave off is primarily a function of machine utilization. Period. The utilization % break even point for idle vs. turning the heat off is calculated by comparing th

Hi, Thanks for the reply guys, and this is interesting information. I had assumed that if we had a paste spec, and this was the spec for the solder to reflow correctly, then if I achieved that spec, the solder should perform correctly. However this

You will have to machine the part off down to the top of the balls. Wick solder off from individual sites one at a time. All that will be left is Parylene shell where balls once were. Take an orangestick and alcohol to break up and remove. Tricky par

If there is dust (on the glass) off from the center of the lens it will add it to the part when scanning it and place off. I have ran into this twice.....I fixed it once by breaking the lens on the quad align and blowing it out.....another time I hel
