The 740 has been a great machine for us. We've been able to reliably load components as small as 0603 (we've not tried 0402, but I believe with a special nozzle adaptor, you can get it to work) and place a 7x7 56 pin QFN with 0.4mm pin pitch with hi

Hi Phil, thanks. I am successful using the same connector on small thinner boards 2-2.5kg) i cant make it work, tried all kinds of profiles with vapour phase but to no avail. Yes you read it right 4.3-6.3mm pcb thickness and 2-2.5Kg. And it is 44 lay

Hi Smitty, I am currently using Manual Lock Red-E-Set, and never had problems with damaged components. Although at my last workplace, we used VarioGrid, and encountered same problems as you. I suggest checking the pins on the support tools(s) you h

Could anyone please tell me if there is a quick simple formula for working out the ideal SMD footprint for a 52 pin QFP using the dimensions specified on the manunfacturers component drawing. I know of the IPC 'SMD land patterns' standard, which I e

Hi, - any suggestions welcome... I have a 484 pin ALTERA fineline BGA - ball pitch 1mm (40) - ball size 0.48mm (18.9) What would you recommend for... 1. Surface pad size for the balls of this BGA device? 2. Stencil thickness/type and hole a

I like MPM's 500 machine. I purchased the predecessor model when it was made by SMTech. This machine has programmable pin supports which made setting up for double sided boards really easy. For auto alignment, I think only in-line machines have th

Dave- this may not be much current help but for future needs: IPC-7525 Stencil Design Guidelines is due out real soon. Check with IPC on its status, last I heard it was in interim Final.What is nice about this Doccument is that it also covers Pin_Thr

George, Did you ever get to the bottom of your XY offset issue. I am a user of Protel and SMS Linecontrol, and know the system well. You probably need to find out if the Protel XY is the component center or Pin 1. The SMS Linecontrol Protel modul

I am looking for tooling plate manufactures. I am kind of new to the SMT process, well as far as tooling goes, and I am trying to find a machinist to make tooling plates for Fuji and Siemens placement machines. Does anyone have any recommendation f

Hi Jason, a couple of questions: What�s the pitch? Did you change direction the board is going through the wave and what happend? How about the design abnormalities for those 4 pins, thermalreliefpads or whatever? We had problems with 2mm pitch and
