In general, cleaning with deionized water is acceptable for most component. Open switches and contacts, in general, do not get damaged in this process. A good drying is required, of course, after washing. However, you've described dewetting issues

I don't have experience with 1B73. I do have a ton of experience with CE-1155. There are a couple of gotchas with this material. First and foremost is that it HATES silicone residue. If the material is not sticking to parts and they aren't cerami

Hello, I have no experience with CE-1155 but a ton with 1B73. I would say Justin hit it right on the head. 1B73 does not like to be anywhere near silicone residues. We make sure the boards are handled with gloves after wash, before coat. Unfortunat

Vacuum Soldering is mostly available with Vapor Phase Soldering systems as a option. Asscon / IBL / Rehm Thermal all offer this... Rehms system is unique as they offer in place solder and vacuum vs the other two vendors that move a PCB with Molten

You should do some testing what temp you really get. Solder will melt 260~300ºC. Back to the initial question, CEM-3 is a bit harder to buy and has not many varieties. Go for FR4, you can go for a higher Tg then the common 130ºC. There is also 140,

I have the part you need. The Yamaha Part number is K39-M7173-000. The same part is used on Philips machines using a different part number. This assembly is expensive because the motor is attached to a Harmonic Gearbox and encoder. I have a new unit

Louie, We'd be interested in your experience with the stainless centering jaws. We just ran a job with heavy 0402 placements, and had a rough time with it. After much work on the package, magazine centering, etc, I've concluded the issue is the ce

not just speed, looking to reduce down time on having to re-do boards from bad stencil screening. also, the accuracy of placing solder paste down on PCB's. why would you want an employee spending so much time aligning fiducial marks from panel to pan

good point Sibbe, we also do a lot of engineering and changes from rev and having to order a new screen very time is a pain and money spent. no more having to wait for a screen to keep production running. has anyone been working with a solder jet pri
