Try a rosin flux this has solved it for me on numerous occasions, no need to use heavy rosin only around 4% total solids so rosin around 1.5% is sufficient. It is down to the plasticizers which are tacky coming out of the resist. The rosin is an imme

We go through maybe 8 a year. We have 2 lines with LCS and each traverser has 4 pads so that would be $856/yr for 8 pieces of foam. I know they are custom made but I am thinking if I could find the right foam I could make these myself. I was told

Is anyone using any NanoStar components from TI? It looks like we might be building boards with some soon. We have put down 0201's successfully. But these are a whole other ballgame. They are 0.9mm by 1.4mm with 5 or 6 balls on the bottom. Would thi

Thanks a lot guys. The part dims are in mm by the way. So last night i was looking at the .pcb file and saw that the pad size and stencil are both .013" while the ball on the BGA is .018" (sorry for switching from metric). Is this ok or can i have en

Hi, Have you looked at Siemens F4 & F5? Regarding PMJ from experience I'd steer well clear (i.e. initial cost, flexibility, cost to add functionality at a later date), however a good second user or remanufactured GSM makes a good odd form placer & i

Juki KE-2050R (or any of their R-series machines). They have the ability to automatically learn pick positions on paper tape feeders and they can zoom in on pick locations (x2 or x4), so this will help when they release their nozzle for 01005 compon

On the non-wetted holes put a solder iron to them and see if they "bubble" if so, you have some outgassing in your PCB and they will need to be baked prior to assembly. If this is okay I would investigate the grnd layer that was mentioned. What is

Hello all!! I currently have this thought, of maybe producing my very own type of feeders. Say juki,panasonics,etc. but building,design,and production of my own. What would be preventing me from doing so? Let's say i wanted to build a Fuji CP-4 feed

Ok, I just need someone to give me some feed back on a few questions I have. If anyone could help me that would be great. Example: take a Fuji CP-4 feeder for instance! If I machine my own, place my own parts on it, and place my own company name, and
