Philips Topaz - is there any way to use it to place parts 11 - 13mm tall?

Electronics Forum | Thu Jun 27 12:45:03 EDT 2019 | jmoote

We have two Topaz machines,and use them regularly. However, we have a board that contains a standoff and a large electrolytic cap, and one is 11.2 mm high, the other 13mm. Is it at all possible to modify or upgrade the Topaz to handle these parts?

I have tried the IPC calculator and they do not have this type of component registered. When trying to select 'other' on menu, no connection can be made. The polarity if the QFP has not been decided yet (pre-PCB design) the pitch size of the componen

Destacker will not separate 1mm thick boards

My UIC destacker does fine with 2mm thick boards. However, I have to hand feed the 1mm thick boards. I have seen vacuum board placers for small boards but not for large boards. I need to get a solution for 24" x and 16" y boards that are only

hi, i have a question relating to fiducial, is the fiducial normally comes with the pick and place data from the custommer or we have to define it by ourself? how to set its coordinate so that the cp6 and ip3 (using Fujicam software) will be able to

KT, What sort of delta T are you getting? This does sound a bit odd. TCs are in EXACTLY the same position on each board? Something I only recently found out - according to Mark Cannon from ERSA re profiling, that you may wish to consider. 1.TCs sho

QFP footprint -extended outside pad?

G'day folks - haven't been around for some time but still soldering on. Question for y'all. One of my design engineers has shown me a Creative PCI audio card with a TQFP48 attached. 0.4mm pitch. Let's say the pin width is 0.2mm and the pad design ha

How important NSMD pads are for the QFN and similar packages?

About the pads shape - you can do rectangular or oblong. For stencil design oblong is better for small pads(0.2mm) because it will give better release, so having this thought in mind you should probably design oblong shape and then print make paste a

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
