Zac, for the profile I mean both - if your machine temp profile is inside the process window of your flux. Trying other fluxes might give you some answers.

I recommend examining the problem pads and a representative bare board using SEM/EDS to determine if the problem is related to a board solderability issue. I can support this type of analysis (www.semlab.com).

Thanks Ed. I'll keep that in mind but at this stage I'll rule out the other options such as flux and heat profile first...

My best suggestion would be to write a contract that says "payment in full upon our acceptance." The problem with used pick and place is getting support. All of the manufacturers decided that unless you bought the machine from them, you are going to

Tsvetan that really is an amazing machine. I have looked at it but assumed it was way out of my price range. Is it really possible to get a new machine with 50-60 feeders for under $100k? That sounds like a steal. What is the maximum component heig

I'd be surprised if you find a non-destructive method of removing carbon ink. Your best bet is following the recommendations of your ink supplier.

Carbon ins has very strong resistance to acid and alkali, not easy to remove, maybe return your boards to PCB supplier? they may have solution. Robert Peng- SysPCB

By the way that you stated your question, I assume that you want to do something different with the carbon inked pads. If that's incorrect, instead of removing your carbon ink, considering printing an insulating layer over the ink.
