I am currently looking at new pick and place equipment and have come down to these two machines. I am interested on hearing from users of both, the pros and cons of their choice. I am a low volume high mix OEM upgrading from Quad QSX-1 and am interes

Ask 10 cost accountants to cost out a PCBA and you will get a dozen answers. I think what you are asking about would be even more difficult than that effort to create a standardized BOM format. You might want to contact Juki. There biggest sales pit

I almost forgot; If the pcb have HASL (Non RoHS) surface finish, then big fine pitch QFP:s could be shifted during reflow, beacuse of the un-even pad-surface... We have been trough that scenario also... But step No.1 is to make sure that the componen

I'd say it all depends on the CM, and how they cost out their production floor. I've seen everything from a flat cost per component placement (something like .05/machine placed smt part, .15/machine placed tht part, .25/hand placed tht part) to stra

We have Siemens Siplace Pro software for our Siemens equipment that allows you to overlay the solder layer against the placement data to verify placement,part rotation and part size are correct.Since we have been using this software we have not neede

We are running an upgraded, refurbished MyData TP9 machine in our high mix, low volume production. With those improvements it does okay on the 0402s. The TP platform is no longer in production but they are still providing good support for machines

I would suggest accepting components only in paper tape. I have had better luck with 0402s in punched paper over plastic embossed tape. You can also pick with oversized nozzles if your vision system does not give you trouble with seeing the nozzle.

Hi, We use the standard pin supports when necessary. Are your boards very thin i.e less than 1.6mm ? or maybe panelised ? Other things to check are Z0 placement height aswell as damaged nozzles,sticky nozzle/nozzle head , poor feeders along with t

OK , the H6H file is a binary structured file and can be read if you write a program in VB etc to extract the info you need, would take some time to sort out where to get what in the file, juki would no help you here.... Assuming you need placement

Brick (if that is your real name), Placement machines use centroid data to place parts. Generally this is derived from the "copper" that is etched on the board. Thus why we use the fiducials for alaignment. During board manufacturing, holes are d
