Mark, You should have enough feeders to build your largest board and have your next largest board loaded up to run as well. Unless you only have one product you will quickly find out that changeover time can really kill your productivity. Keep in

Low-consumption Nitrogen configurations with an on-board O2 analyzer is the ideal way to go. I cannot speak for all oven manufacturers, but ours have N2 fed to the reflow zone only, which to me is really only where you need it. The gauges/flowmeters

Hi Grant, You say your design are increasingly using more passives. Do you mean you're using more and more components per board or is it only the ratio passives/IC's that is shifting? And are you also increasing volume or is it just the component-co

Do you have an automated line with pick and place equipment that can handle your BGA's? Inspecting the board is a must after profile development. You may send the 1st board to a CEM for X-ray inspection. If you have a consistent process (printin

You may want to complete some due diligence before selecting the right software vendor.....knowing after selection that you're kinda' stuck for a while. Find out support for your needs (feeder setup lists dynamically created, easy board views and po

I have never heard of steaming PCBs. Wouldn't this induce moisture into the PCB and cause more delamination and out gassing? The only way to fix delamination, providing your manufacturing processes are in line is to find a new PCB fab house that can

UPDATE The reason for the board count in the wave when there are no boards is due to operators leaving racks with empty PCB slots. The input feed sensor is a little bit more in the center of the conveyor whereas the output feed is a slightly closer t

We have a customer that at one point had a dozen LED boards that were all very similar in size. They used Aluminum boards and I found that the difference in thermal mass between the assemblies was negligible considering the largest difference was ac

Once you have the capabilities to track a board from the initial stages in kitting all the way out the door in box build the possibilities are endless. You will now have: 1. An exact count of your companies WIP. 2. The exact location of every board i

I'm having a fun time between BGA rework/repair using an SRT 1000 and SPC efforts (much easier) using DEK stencil printing processes and BTU reflow with 6 Fuji lines in between. Concerning the BGA stuff, I'm getting about 60% success using this rewo
