Hi Joshua, We ran 150K per week this way, you just need a lot of pallets. Regarding dispensing I've seen 0201 (Imperial)paste dispensed, so about 0.4ish mm dots. I'm sure the Mydata printer is also pretty high resolution too, but not too quick.

Hi Joshua, No, the adhesive lasts 2 or 3 runs. The adhesive is put on manually as is the kapton. It's a big panel for a flex - nearly 300 x 210, so the operator loading the boards onto the pallet and fixing them (then into a buffer) stays well ahe

Hi all, I'm wondering how does one decide to use flux dipping or solder printing when it comes to be attaching CSPs onto the board? Solder printing has an advantage in that there will be a higher throughput on the mounter as there is no flux dippin

If there is no specific quality reason, stay with paste. More processes you add, more points of failure. They don't need a lot of paste to get attached to the board. The ones I used were 8mil round apertures, so I did cut 1:1 on a 3 mil coated stenci

80 micrometres (0.08mm) or 80 mil (2mm)? Smallest I've seen reliably printed is around 0.2mm x 0.4mm (01005 pad) and 0.2mm x 0.2mm CSP pad, not seen anything dispensed below 0.35ish, but we are not cutting edge.

Hi Ivam, 1) for the not working motor, can you swap it with another from the cooling zone to see if it is the motor or motor control? 2)You are not getting bleed through from one zone to another are you? Can you list by zone what exact SP you have

We're looking to add conformal coating to some of our pcb's which range from 2x2" to around 6x6". I would like to use a coating material that is not nasty smelling requiring ventilation or filtration if possible. Are there conformal materials that ar

Not sure exactly what kind of coverage your looking to get but we use Dow Corning 3-1944, it's room-temp cure and rather thick, (think warm honey). But we have found it useful on several projects. http://www.dowcorning.com/applications/search/produc

Thanks for the tip. I'm still getting familiar with the machine by reading the manuals as I have time. Was wondering what type of solvent you use to clean the dispensing mechanism parts? Or do you not clean anything and simply dispose of the syring p
