Scotty: If you have excess CNC machine capacity, it might be economic, but if your machine and design resources are loaded-up the $1000+ sounds cheap. [Just another voice screaming in the dark.]

Presently I am looking to buy either a PDR X410 or ERSA IR550A rework mahine.The PDR model is the favourite at the moment however I would not turn down the ERSA model or any other similarly specified infrared based rework system.Unfortunately I have

Change pastes, although insufficient heating may leave excessive residues. Is this on one board or all products? No Clean or water soluble? Do you profile accurately or "guesstimate" your settings?

Has anyone had issues where bottomside double reflowed smt has fallen off in the wave when using voc-free flux? I have verified the hotter profile was not the issue by using an alcohol based flux with no problems.This voc-free flux is also not causin

Good morning Dr. Lee. I was wondering how flux chemistries have changed, or will change, with the transiton to Pb-Free, given the higher reflow temperatures required for SMT assembly?

Dear All, In order to understand the soldering technologies in SMT, I'd like to understand why some cards are soldered and then cleaned, or only soldered whitout water cleaning nor "ultra sound" wavelength. I mean that I wonder why we use toxic flu

When we hear the words 'flexible circuit' and 'delamination' in the same sentence, we think: * Excessive reflow temperature. * Entrapped moisture. Boardhouse: I hope this is a step towards redemption.

I require some feed back from any one who knows about using a voc free flux in a nitrogen wave solder machine soldering both through hle and smt componants. What disadvantages are there when using this flux? Do you have any contact details with any o

Glenn, i am aware of one unique problem with voc free fluxes. since these fluxes have certain amountb of water content they cause sputtering leading to solder balls & voids problems. Regards Vinesh Gandhi | I require some feed back from any one
