Flux: No-clean pastes tend to have a wider print process window in terms of print speed and pressure. More importantly, no-clean pastes are more tolerant to changes in temperature and humidity. They also exhibit longer stencil life than water-solub

Just to let all the folks no. If you register (and pay the fee) a machine with any (OEM) company in the USA You have the same rights as a new user. Companies like UIC, Gen Rad, Agilent, etc came up with these fees to discourage buying used equipment.

Good job clarifying things. So, your MELF are just rolling off the pads. So much for the rocket scientist that talked you into those �V� shaped apertures, eh? [Or taking it the other way: Wow, just think how bad it would be if they weren�t worki

Haaaaa!!!! Soldering to plastic!!!! An apt analogy!!! I like to compare it to soldering to dirt. Some thing. In fact, you are soldering on nickel, when soldering on many things. It�s just that the gold, er Pd, flash enables the wetting mechanism

Steve, I am not aware of any standards so to speak. But IPC 782 and 770 have some useful info regarding mounting and pad geometries for wave etc... Since I do not know what type of components you will be wave soldering I will just give you some

The follwing is from the Technet archives, per IPC's Jack Crawford. I dug it up during some investigation of a supplier's issues with humidity in an Asian plant: There is support for this in IPD-HDBK-001 w/Amendment 1 Handbook and Guide to Suppleme

First, an earlier poster suggested using DI water. We are NOT excited about DI water with a NC fluxer, unless DI water is the proper flux thinner. Second, as you inplied, the maintenance steps you take should vary according to the amount of time th

gregp Your question started out asking about the advantages of bulk feeding. Based on the discussion it all comes down to costs. I offer another perspective that I believe is extremely relevant. Any advantage in manufacturing has to come down to
