Hi All, We are in the process of converting from RMA solder paste to no-clean process across the shop. This will allow me to carry my semi-aqueous cleaner out of the building and set it ablaze using the terpenes as the fire water. Then I can go ab

This may help you regarding the V-Groove or scored board designs. With respect to material left, I did some experiments and found that for our process .009 of material seemed to be ideal. There was minimal stress required to break the boards apart ye

| I'm also in the "Don't score it" camp. Routed breakaways are much better. If your wave solder process has decent control on the wave height, you shouldn't worry about flooding the boards. | The fine pitch consideration for panelizing - Since you

More lube on the O-Rings caused lots of problems. Nozzles would drop downward at times. So I pulled everything out and started from scratch. Testing 3 new Z-Rods, 4 used Z-Rods in good shape (replaced the O-Rings) and around 20 nozzles - the proces

Masdi, Try board shunts. They are hi-temp rubber strips with grooves cut. They can be popped on and off with ease and are much faster than taping and considerably cheaper. They also work great for masking goldfingers prior to wave soldering. Contac

It really depends on how you depanel these, If you are using a machine you can probably get away with the 1mm, If not, the 5mm is there to help reduce the cahnce of fracturing the component. Some interesting notes about having a defined keepout is

No Rob you didn't misunderstand, I forgot the decimal point! Lets try this .2" thick (I have built this and yes it was V-Scored) We didn't break any caps on that baby just fingers, that was the wildest VScore job I have ever seen I don't know how the

Thoughts are: * Eliminate solder spotting on gold fingers through process improvement in broard handling, printing paste control, and reflow recipe development. Search the fine SMTnet Archives for previous discussions. * Dispense or print a reflow te

Right now we are taping the goldfingers which is effective but also expensive. Also, some tape was leaving yellow marks on the goldfingers. We're trying the so-called goldfinger glove from Steven's Products. It's a very small company (probably one gu
