Hi All, I'm new in PCBA process. Recently in my leadfree production we encountered a missing ring on some of the ring on the board after we ran hem through Wave soldering machine. The board has gone through double reflow prior to the Wave soldering.

Hi Dougs I worked a bit a few years ago with a diode type soldering laser. I found laser soldering very application specific so make sure you send samples off to differnt companies to see actual results. You can get good results with a laser system

We currently have 5 MyData machines in our facility. Our production lines are the Mydata Synergy package which is two My9 machines connected together and both machines have the Hydra heads in them which is giving us 15k cph and these are rated at 27

Hi, We have a 5 zone oven and we use a RTS Profile. Our last zone is the zone that the reflow takes place. some basic analysis is as follows: TAL 70 secs, peak temp 210,ramp rate seems fine. A typical setting is : Z1 140 Z2 160 Z3 160 Z4 185 Z5 220

The most common rates of in-process cleaning (under wipe) I have encountered are once per 5 to 10 prints. But this depends a on a lot of variables. More often is typically better, but more costly in under-wipe materials. (For some more info see http:

We have a system where when we set up the line to run a job before the first part is placed an auditor verifies we have all the correct parts loaded on the machines in thier correct locations. We then run a first article. The board is inspected to in

Hi Folk, every now and then, i would encounter Functional Failure due to BGA ICs. The Testing Tech always conclude that the contact of the BGA to the PCB Pad is poor. The 2D/3D X-ray machine can't detect any of the poor contact on the BGA..... We

Oven settings are meaningless here. What does the board see? It is the paste we are concerned about not what the heaters are running at hehe. These solder balls are at the end of pad, which end? under the part or away from the part. I believe you

There are a few variables that you have to consider : 1. Hours available on Wave Machine ( are other products going thru the same wave) 2. What beat rate are the boards being supplied from previous station?i.e. do you envisage the waveto be a bottl

We just bought an Advantis w/flexjet head. Great machine. No problems with anything and Universal support is excellent as always. Prec-Pro dual lane feeders are the way to go. Also, I recommend buying the NPI module. This software allows you to
