Are there specifications or recommendations for electro-deposited tin-lead plating thickness on austenitic stainless steel that would provide a shelf life of 1 year? 6 months? Would 2 to 3 microns (78 to 118 micro-inches) 90/10 tin-lead over 1.27 mi

Also in some instances a 10% decrease on glue size would be needed for the smaller S.O.T. sizes out there. If you are dealing with a good company to make your screen they should send you back a preliminary art work file on the Screen to be made so yo

Why don't you have stencil house make a selective wave fixture for your product so that you can avoid the glue problem. If it's a must for your process to have glue, you just add extra work and glue tended to contaminate. Just a suggestion..if you

Don't feel alone. Many assemblers have the same problem but aren't fortunate enough to have say in the design of the board. They're either have a capital invedtment in a selective solder machine or pallets designed to mask bottom-side SMD. The pal

We bulid many boards with fine pitch on solder side and then wave. We use a wave fixture that is custom for each board. The fixture covers the SMT components and only exposes the PTH lead during the wave process. It requires about .070 to .100" clear

Once you have selected your plating based on electrical and physical requirments, you should know that there is an inexpensive plastic storage packaging developed by Lucent which can keep any platings solderability from degrading for up to 10 years o
