We got a good deal on ours for around $100K new with not many options. For what its worth I visited Novastar's factory in Pa and was not happy with what I saw there. There were almost no static precautions taken, boards were stacked in cardboard boxe

TAL Too Long - dull solder joints, dewetting. TAL Too Short - cold solder, insufficient wetting. You want TAL to be as short as possible (but not lower than 30 seconds), but long enough for every solder joint to be above TAL for at least 30 seconds.

First off, go with HiE (Hi Efficiency) machines only. UP3K and UP2K have huge differences- board size, speed, options, etc... too many to list really. I would recommend UP2K HiE over UP3K HiE. Its a simpler machine and easier to find on the used m

Soldering PTFE boards * Exposure to the high temperatures needed for solder reflow poses no problem of loss of peel strength since the exposure times are relatively short. * There are many different types of PTFE based products that may perform diff

A solder wire classified as L0 under IPC J-STD-004 means that the flux residues can be left on the board safely, and when you select this type of cored wire the intention is not to clean. You just select a solder wire that gives you an acceptable lev

Let me give you some good advice You take already plenty of risk going lead-free, DO NOT use halogen containing fluxes in a lead-free no-clean process. Halogens left on the board will convert tin, silver and exposed copper into metal salts over tim

Dear ERhard.Our placer are Universal Genesis machines and the screen printer is DEK Horizon 02i . for Maian board the tact time in the placer is about 14 Sec and the printer is about 22 Sec. Means there is a big waste time . for Front pannel we are u
