I'm now have target to flux saving. Could you please tell me. If we adjust level of spray fluxer nozzle up then we can saving cost of flux Quantity usage? What Others must adjust? such as pressure , flux flow. Thank you All for advise.

Hello Armando, this is what I found into the handbook "Failure Analysis of Electronic processes" : "...Flux residues with water-soluble flux activators that are conductive and corrosive if left on in large enough quantities are detrimental. If you

Hi Walter, Do you refer to a sprayfluxer operation? The problem seems to be a parameter setting issue. 1. Ensure the wide angle spray reaches PCB with optimum jet pressure. You could pass a glass plate to understand flux coverage and view Jet pressur

If you have flux deposits on the cooling plates, try out Zestron's VIGON RC101...It is an extremely good product especially for reflow ovens and wave solder systems. Check it out...Minimal maintenance water based chemistry with no flash point...Much

Hi Jeff, Sean is correct. Although ultrasonic technology will work in post-reflow de-fluxing applications, you will receive concerns regarding ultrasonic �damage� to wire bonded components. Much has been written to combat this belief but the conce

Wes, I have been involved with many customers changing over from an alcohol based no-clean to a VOC-free process. The change-over can be made easier by such things as air movement, convection preheat, "drains" or reliefs in pallets (if used), contr

Hi, I need some information about the relation between the type of flux used in wave soldering and the quantity of dross produced. Thank you in advance for your help Mohammed

Yes this is absolutely true. No-clean flux residue has various affects on the functionality of circuitry especially high impedance circuits. It also affects solderability, and reliability. No-clean flux will always leave a detectable residue. Mos

Hi George, I would suggest you to re-look your process parameters, especially for the pre-heat temperatures and the amount of flux deposited. The mask properties and that of your flux also play a role, but you could zero down to the root cause after

Echoing SheanDalton's comments [above in this thread]: * A good way to strip part markings, solder mask, etc. * A fairly aggressive against most polymers. * A flammable material. * VOC issues in its use. * Assembly workers don't like the smell. * A
