Hi, I am looking for opinions on closed-loop inline washers. We use water-soluble paste and flux, most of our boards are double-sided, and our finest pitch is 16mil, but we will be doing BGA, uBGA, and possibly flip chip in the future. What would

Definitly evaluate the TD washer smt 324 / 318. I have two units and they have been fantastic from a maintenance point of view. Small, quiet and easy to maintain. I am in the middle of cleaning capability and ionic contamination testing as we spe

Dave, Not sure if I understand the question. We do not process No-Clean in our facility at the current time. We are a completely Water-Soluble with a 12 year old Hollis Polyclean In-Line washer. I need to scrap the piece of ****. That's another

Never heard of Bareco wax. Check with your press supplier. They'll have the dirt on this carnuba oil stuff. I do question replacing ENIG with HASL, no other changes. HASL is going to fill that hole alot more than ENIG. Certainly it will displace

Hi Greg, You sound like a buyer or procurement professional. Everything you listed is OK, and more or less. Quite often Engineering Design or Product Management in the OEM establishes what they feel are some of the basic T&Cs. I guess I would ask

Hi I don't see in your note any particular reasons why you couldn't. If it solders well and passes what ever specifications you are using than everything is OK. If your repair faces some soldering or rework challenges where a more agressive flux is

Does anyone know of any free software that would allow an inspector to look for a reference designator on a densely-populated PCB? The software would need to accept a CAD pick'n'place file as input, and highlight the part when the inspector enters t
