The need to Pre-Bake depends on multiple variables: 1. Packaging from the vendor (dry packs, vacuum sealed, etc...) 2. Storage at your facility (temp, humidity, etc...) 3. Moisture absortion rate of Laminate (FR406BC is one of the highest) Other rea

Definitely better than foam!! I personally love the sonoteks. They do not really use a "nozzle" by the way. The flux is pooled on U.S. head and it atomizes it and then you have air spray to form proper spray pattern, If you are using Water soluble

We have 2 PVA2400 4 axis selective spray machines that we use to spray Humiseal 1B31 and 1A33. They take a bit of programming to get right, though this is easy to do, but do the job OK. Another to consider if you need the 4 axis of movement would b

I am personally in RI, but my HQ is in San Jose, CA. I can get you more information on the machine(s) and configuration you have though, if you are interested. We are also one of the few Used Equipment guys that will sell on terms and stand behind

I'm reworking lead free BGAs now, on a Conceptronics Freedom 3000. I use flux only (no-clean, Indium) all the time, with no issues. If you go to paste, you also understand that you still have to hit the same temperatures as with flux, as the solder i

Can someone advise if there is any risk if we use lead-free alloy wire during rework for Leaded Process?The reason for this proposal is to only have one type of solder wire being used in the line.This will eliminate any possibility of leaded wire bei

Dear all, Do you know any simple method to measure the bending strain on a PCB. I have heard of something like a special tape that changes colour when bent. This can be stick to a PCB to find the bending stress/strain but I cannot find anything on t

What are the main advantages of having a Zevac DRS 22. I just completed a through hole and SMT soldering course and I am thinking of investing in the DRS 22. What are the chances of getting a return on a $10,00 to $15,000 investment doing rework an
