I won't say never but very rarely do we have problems with the flux seperating. The way we get around the 1-2 hour warmup time is this: The day before we run a particular job, the last person takes out the paste needed from the fridge as the last t

I am curious as to why you need to mix.... We use a 500g cartridge with air gun. Our process is remove the cartridge from the fridge, allow it to warm up to room temperature before inserting into air gun, then apply bead of paste to the stencil. N

We've used mostly cartridges for many years and I only saw separation once when a particular paste supplier had a problem. With cartridges it's just thaw and use - no mixing. We have some sites that use jars along with mixers and I've never been co

Sorry i wasnt very clear we already have a Malcolm sps-1 for our tubs but to move over to cartridges we need a machine to do that none of those machines are capable of mixing a 6 oz cartridge

We bought air dispenser guns that fit the cartriges. I can't remember where we got them - sorry. We built little aluminum "holsters" for the sides of the machines to put the guns in. The guns are hooked up to air with low pressure regulators. Wor

My group supports a couple hundred lines all over the world. Most of them use squeegees but a few use either the MPM Rheometric pump heads or the DEK Proflow heads. I absolutely hate the enclosed heads. Flux separation, compaction, and the print q

Thank you for the reply, Davef. I am thinking if I can get the standard rather than "trial and error". If there is no such standard, is there any experience of what is the range for good and acceptable solder paste (e.g. minimum and maximum percenta

Guys, If there are any specifications or ciriterions for solder paste deposition thickness and volume evaluation. For example, QFP (0.5 mm pitch), 6~8 mils, 3000 mil^3 PLCC: 8~10 mils, ... . . Thanks in advance. Best Regards,

I'm in a manufacturing environment with a very high mix of boards, and some low-mid volume. A "large" production run might consist of 100 boards. Volume: There are numerous boards that have a volume of 1-3 pieces. There are a few boards with an annua

We use the ASC vision master 212, our customers wanted a height and volume measurement rather than an inspector doing a visual. We have added this machine to our process, checking height on many preprogrammed locations then this generates a X bar and
