soldering irons for lead free

Electronics Forum | Tue Jul 12 09:51:42 EDT 2005 | russ

We use the JBC irons with and without the "leadfree" tips. We really have not noticed much difference between the standard and the lead free. The lead free tips do last a little longer but the tips are somewhat deformed by the extra plating. As f

Possible to water wash no-clean solder paste boards?

Electronics Forum | Thu Jul 14 09:42:36 EDT 2005 | saragorcos

Our facility helps customers clean no-clean soldered boards on a regular basis, and it definitely can be done but is a little more challenging than boards built with water soluble flux - one piece of advice I would give is to use low water pressure (

Hi everybody. I would like to know if any of you guys is using the HP5DX output processor from Assembly Expert to generate de .NDF files for the 5DX machines. I tried but I got a lot of errors because de configuration file for that processor needs

Baking prior to conformal coat

Electronics Forum | Wed Jul 20 10:07:05 EDT 2005 | cecil

Does anyone have any input on the need to bake out an assembly prior to the conformal coat process? I understand baking out components/pwb's prior to processing through the reflow or wave solder process if the material shows excess moisture absorbtio

Nitrogen Reflow - a source of BGA Voiding?

Electronics Forum | Tue Jul 26 08:20:46 EDT 2005 | Bob R.

All you can do is try it. I did a literature search last year on causes of BGA voiding and came up with a pretty long list, sometimes contradictory. I also discussed it with several paste suppliers. What I came away with is that what aggravates voi

Stefan, Was this machine a Fuji by chance ? Did you buy this machine ? If so why would you or anyone buy a machine sight unseen that is "way overpriced" Just curious.. I have been told by representatives of major SMT machine manufacturers to BEWARE

Quad IIIc/IVc programming question

Electronics Forum | Wed Aug 10 20:30:49 EDT 2005 | slthomas

I've got a new board (actually a new panel...a 4 up, with one row rotated, where it was a 2 up panel with no rotation before) that runs fine on the IVc but not on the IIIc. I've used the same reference points for the image rotation (fiducials) on bot

Matrix Trays

Electronics Forum | Fri Aug 19 15:45:45 EDT 2005 | DannyJ

I usually like to have all the trays use pin 1 in a certain direction. In other words, as you are on the operating side of the machine, all the pin 1's should be on the lower left of the tray. With operators, the KISS principle seems to be necessar

Laser Marking

Electronics Forum | Tue Aug 30 11:23:07 EDT 2005 | g2garyg2

AJ, there are a variety of laser marking systems in the marketplace. Most use a CO2 laser to mark PCBs. Since laser life is directly related to power available vs power used, you should try to get a system with a 30 watt power rating. Most marking i

ERSA versa as alternative to wave soldering in low vol high mix

Electronics Forum | Mon Aug 29 12:52:21 EDT 2005 | pr

We have 2 dual head Versa-flows in line. We use them mainly for doublesided reflow jobs that have connectors and axial parts. I have about 15 jobs currently running on them. The advantage of having 2, is some of our boards have through hole on 1 side
