I have been using Alpha 856 for about 8 years. It is an excellent flux. Today we are using it in a new flow solder machine that has a spray fluxer and it seems to be working fine. I can be contacted at jlalicker@amitulsa.com

Ask the distributor (or coilcraft) what the termination material is & if they do alternative ones. These maybe from old stock. If you get no joy have a look at Epcos & Murata who both have wide ranges of surface mount inductors.

Thanks Rob. We've been in contact with Coilcraft, but haven't gotten anywhere, yet. We'll check out the other coils. We started using Coilcraft because of their high Q.

We have just purchased a humidity logger and I need to know what the relitive humidity should be in a SMT production area. The Room is enclosed approx. 60ft by 30ft using ESD Floor tile. 3 machines are in the room as well as some Thru hole machines.

Where in the world are you? Is it naturally that dry and you'e trying to keep it up, or do you dry it to that state? 'round here 40-45 is the norm so we don't put much thought into controlling it.

From ambient, about 25C, that's to peak overall to about 230C. Dave's got the link to the SMQ 230 sheet.

We assume your stencil is clean. So, try: * Reduce stencil separation speed. * Reduce squeegee pressure. If the pressure is not proper, excess number of particles are stuffed into an aperture and inner pressure / friction among particles increase, an
