SPM is superior. SPM has larger print area, up to 20� x 19", vs. 17.7� x 15.7� for the UltraPrint 100. UP100 is microprocessor controlled while the SPM has a PC. The SPM cameras can be positioned more rapidly and with greater accuracy than UP100's.

Component manufacturer often have recommendation for pad layout and process setup. This should be used as a guideline to help You to set up the process. Exactly what type of component is this, uBGA? We populate 64 I/O uBGA's on our pcb's with 0.3 mm

Martin, may I ask what your offer is? Does the pick and place machine vendor provide you with a special nozzle, which would not require the peel off cover. Custom nozzles from the OEM are quite expensive, because they implement engineering and test.

We had a V-Tek TM30 manual taping machine using heat seal top tape. Had very good results- with skilled operator - to supply taped components to our 2x Fuji IP2 machines - no tape cropping. Stefan's points are somewhat valid, but you can have a succe

Do you have a bake oven that will reach 200C? You could bring a batch of boards up to temp and then start the pluckin'. A sfar as the solder goes if you apply flux to the leads they remove very clean as far as solder goes. To remove the flux we pl

The BioAct SC-10 wipes work great, but I've noticed some contamination in our solder joints after I began using them on the stencils. After cleaning the paste off the stencil with the wipes, I started spraying the stencil down with isoproponal and bl

Is this problem really related to the size of the BGA OR the size/thickness of the PCB? Would I be correct in assuming that your pre-heater is small in size? Usually a board warps like this when the ramp is to great at the localized area. the imme
