I used a Balston in another life. It wasn't large enough to provide for reflow or wave but they made them large enough. Maintenance was minimal, problems were virtually nonexistant, and like MikeS implies, the airflow requirements are substantial.

Large Format Printers

Grant, Look at Surface Mount Techniques: http://www.smtprinters.com/printers.html They make fully automatic printers that will print PCB's up to 30" X 60" and 1" thick. That's pretty large format if you ask me... Steve

Voiding in LGA (LT) soldering

Electronics Forum | Wed Sep 01 10:15:44 EDT 2010 | arjan

Dear Sachu_70, During the tests we also checkt other devices, there are a few small voids visible, but they are marginal. We only see large voids in this device. During the testruns we tried several reflow profiles, but without large succes.

Reflow oven profile

We run double sided boards that have large SMT electrolytic caps on the top side using the same profile for both sides. The trick is to do the bottom side first, then the top side. That way you do not need to glue down the large caps.

Rework Station for Large PCBs

Hey, thanks for your response and the information on the TF2800. Would this be suitable for PCBs up to 30 layers? The specs of the bottom heater are quite low in comparison to other "large PCB" rework stations. 1000W bottom heater whereas most are

FR-4 will be OK for small products such as cellular phones. Here the temperature gradient across the board may be 3-4C only, and the board temperature can be well controlled. At temperature above around 245C, the discoloration and delamination may be

We have come across this where the operator was using thin gauge solder wire (more suited to fine pitch SMT soldering) to form large solder fillets (power connections or sheild cans). We found that the operator was feeding large amounts of solder wir

Good Manual Printer for Large Boards

Electronics Forum | Mon Dec 01 12:13:07 EST 2008 | markhoch

Hi Grant, Just a few questions if you don't mind... How large is this large board? What type of packages are on this board? QFPs? BGAs? Is it a double sided assembly? I would almost recommend just purchasing a stencil and taping PCBs down to a bench

Large Footprint Flex PCBs

Electronics Forum | Wed Sep 30 12:58:35 EDT 2009 | markhoch

I'm just throwing this out there, but is anybody manufacturing large footprint flex circuit PCBs? (I'm talking assemblies 18-36" in length) We're in the midst of quoting a new opportunity that involves several flex circuits of this size. Currently o
