Is there anybody out there doing this scenario: SAC 305 Reflow & SN100C Wave and Selective Can the 2 alloys be mixed on 1 board, say, SAC 305 for SMT, and SN100C for thru-hole? Are 2 different rework chemistries needed, or can one use SN100c wire

Does Ekra or MPM require stencil fiducials be filled with Black Max or some other black epoxy? We still require our stencil supplier to do this. I did not have to do this on any Dek solder printers since 1997. Can the MPM UP2000 HiE fiducial light

We have five 1997 DEK 265LTs, and we have never had to have the stencil house blacken any fiducials. The fiducials are etched about halfway through the stencil. You can adjust the lighting in each individual program, not just a global lighting change

we use A EKRA X5 it can use A pad our the fiducial I generaly use A pab becuse most of our stencil don't come with the fiducials on them and our boards our HASAL and the fids our domed most of the time the smt pads work better for me

CK, I'm also "CK", but have been C.K. since way back. See my old posting, from 1999: http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=2819&#Message11498 Anyway, I now go by "CK the Flip" to avoid confusion to this f

Bert, Clean the emitter disk of the nozzle you use for this part. Set everything in the PD back to where it should be and set the "Lead_check_area" to 10. This will look at 10% of the end of the leads. This will help if the leads do not have even

1. Can anyone tell me about the water absorption(wt%) among different PCB((i) RoHS, (ii)non-RoHS, (iii) Halogen free)), I am currently facing the problems of PCB blisters after reflow process. 2. Also, please suggest the baking period/time among dif

I am not familiar with the YV100XG pick & place but you might want to increase the mount height of these components The double stick tape isn't as thick solder paste. it might be pushing the component too far down causing it to twist. I encountered

We would need to set up a line capable of placing ca. 70 million of components/year (preferably in one shift). It will be single product, so changeover is of no importance. Also, there's no need for extreme precision. I would prefer two separate line
