"Can we reuse the same machine? My point here is that the non lead free process has already coated the machine interior ( exhaust, internal flow ) with leaded component, and by conversion to lead free are we containminating the lead free product from

I find is fascinating that a lot of people blame the Pbfree finish before anything else, as if this is some new and scary thing. It MAY be a contributing factor, but I doubt it is the main or only issue. When we started evaluating our BOM's 1.5 ye

Good Morning All, We have recently switched to Kester HM531 solder paste due to some extreme environmental conditions. It has worked well and allowed us to continue production where we would be down with our previous solder paste. We have seen a re

Hi, I've been searching for comments about this, and found something, but a little old, so here is my question: I'm going to purchase a new P&P machine and have two options: Juki 2060 and Mydata MY9. What I need is: easy to manage, easy to change

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

I had Mydata for several years, and got a Juki 2060R about 8 months ago. If I had to choose today, it would be Juki again. The features which help me are bank changing, where I can set up offline and change over in two minutes for all feeders. The

We agree with Ken's points about off contact / screen versus stencil, but this DHolt is talking stencil [regardless of what is typed about screens]. Comments are: * On "smears under the stencil": smearing happens. It makes us wonder about the frequ

Good morning all. I'm trying to find some help on my voiding issue on my lead free BGAs. I am using a Heller 8/2 zone oven, and using Qualitek solder paste. I had listened to a tech representing another solder company, who told me to make the joints

Be careful about taking any generic advice and trying to use it to reduce voiding for your particular paste with your particular boards. I've done a few literature searches over the years on causes/cures for BGA voiding in the SnPb world and found a

Hi, Yeah, it's a nightmare, and we are dealing with suppliers such as Xilinx and many others who have lead times that are now 20 weeks, but they can get you lead parts on 4-6, because they did not plan correctly. Lead free is not something that's ha
