Seeing this graphic has me rethinking solder paste jetting as alternative to stencil printing. It seems it's only 2-3x faster 80k points per hour vs 28k. Wouldn't it be better to get 10 time pressure dispensers vs 1 solder jet?

The purpose is explained in the program 'help' - 'contents' menu. Due to viscosity and adhesion of different fluxes, paste may stick to the stencil more than the board. Using steps allows the surface tension and gravity to pull the paste down; rather

Usually, for big connectors like this, you can use a red smt glue under the connector with a dispenser. If its not possible, you can use the same red glue and put a small dot on the side of the connector after reflow, and heat it a bit with blower, 1

Surely somewhere the cleaning or rinsing liquid gets to the other chamber. It is possible that the chemical migrates to the flush or flushes the chemical into the chamber. I have had a similar situation, high foam, injection vertical spray offline st

We used to use basic stampers years ago to define which shift & operator build which build before shifting to laser marking. You could use a stamper, failing that as the stamper worked I don't see why you couldn't use a basic stencil to mark what yo

I was going to mention this. Make sure the images are where your printer will allow you to position a board. SOme printers will let you "cheat" the board dimensions, but not all. Also keep in mind which orientation you want the board to go throug

We have a few custom made fixtures that use a flat disc like that and they are spring loaded. For our "homemade" fixtures, we generally use screws stocking up in the tooling holes that are cut to only stick up approx .050 on an .062 board, so there

Thank you for your response! I think, the labels seem more elegant and offer the flexibility of being reversible if the labeling isn't satisfactory. However, the punch numbers themselves are also a viable solution, so thank you for that suggestion

Okay, you have only few different product. Smallest package is 0402 and biggest is 144 pins ic. So, maybe you don't need get high-speed machine. You must place about 12000cmp/hour. You can buy quite cheap placement machine. I can't tell what is good

Murad, I have just completed a switch over in our facility to no-clean. We used Alpha 609 and 857 paste and wave flux respectively. We currently use Alpha UP78 paste, NR330 wave flux, NR205 liquid flux for touchup and cleanline 7000 wire solder as
