My first thought is board warp. This is something you can't see when the board is in a reflow oven. I see it occasionally going through wave solder. You may need a pallet with hold down clamps for reflow. Try putting a bare board in a baking oven at

PROBLEM SOLVED :) ! I messed with parameters, then started to check hardware again. and.... There are 2 transport position on the carrier 1) vacuum 2) mech clamp Both have fiber position sensor which shows the status When there is component, the

We do one of two things here; 1. We have cut up a bar of solder to different lengths, wieghts, etc. and place them on top of the offendinding floater, or 2. On selective wave pallets we will build a jig/clamp to hold down the part.

You're on the right track. 99% of the time, it is caused by a feeder not seating correctly. Check and ensure that all your tape covers are down and LOCKED (very important). Which type of feeders are you using Q or K? One thing I have found with K

There are several things that can cause these errors. It sounds as if you have 2 problems. A (Z) problem and a theta problem. 1. Check that the Z-locks are functioning properly in the service program. Make sure that when they are un-locked they don'

Hi John, can�t find that one in the archives. Isn�t all the trouble you may get dependend on the way you design the thing? For example, tight fit with with step/ridge nearly zero and clamps for holding down the inner circle to prevent vibrations. F

I have heard of people using tiny lead-shot filled bags to hold down thru-hole components on circuit boards while running through a wave solder machine on selective solder pallets. How successful has this been? What kind of material is being used f

Hi guys, I'm looking for some tooling parts and I hope you can point me in the right direction. We design basic in house reflow Carriers to surport boards during reflow. I would like to add clamps to our designs but I can not locate any off the she

It's cumbersome. Also if it catches a part partially after initial set-up, you'll get missprints. We had one and caused about 15% missprints. Once removed and hard pin in place, no missprints. Defeats vacuum board hold down too, from all of it's

With the UP2000 that has vacuum board hold down, the Grid Loc hoses defeat the vacuum in order for them to exit the work table. Big boards require more girds, thus more hoses. Set-up between large and small boards takes time to remove or add the gr
