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

I have always been nervous with this process. I fear that the "good joints" may become fractured without coming loose. I am a proponent of this to verify a profile or something to see the strength but then we always reflow the affected joint afterw

I'm confused on nozzle rods as a description. Thru-hole desoldering is achieved by fluxing the the leads that are on the bottom side of the board and then coming in with a desoldering gun. You place the tip/nozzle of the gun against the side of the l

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

We actually did try dots, 1/8" to be exact. We found that they were hard to peel off using just your fingers. Also, the manufacturer punched the dots too deep and ended up going through the backing on many of them. However, using tweezers, it didn

Grant, As a MYDATA user, your comments worry me. You state that the MDYATA's are not stable or reliable? I am currently placing 0201's with the HYDRA head (at appx 15K/hr) with 0.01% fallout/bad placement. I also place a large range of fine p

We use the 3748. We picked it many moons ago after doing product HALT & HASS testing. Basically the run of the mill hotmelts didn't hold up as well under the conditions our equipment lives in. (We do a lot of MIL,Aero & Industrial motor/actuator driv
