Yep, fortunately we have a very good supplier in China for nozzles and feeders, otherwise it wouldn't bear thinking about. Not seen anyone selling Essemtec feeders & nozzles in China, but I'll ask the Question tomorrow.

Yep, especially if they are the silicon domed type that mark easy. We gang pick LEDs on our Yamaha kit, getting 12 at a time per side, but we have the luxury and volume of having multiple reels of the same components.

Good luck, get them to throw in P-Tools as well. Not seen it running with 12 heads, but know a fair few people with M2's & M4's and they rate them.

Hi Stephen, All good machines. Regarding placement speeds ignore what the manufacturers claim, it's utter crap. Start with the IPC9850 number (not perfect, but we have been known to hit it), but even better to make them demonstrate on one of your

MTC = Multi tray changer. It's a stand alone unit that feeds in trays of components - it means you don't sacrifice feeder locations to waffle packs. Different companies call them different things. A 760 is dog slow, and spares are getting harder to

I've seen them down at 2 metres in the past, but usually only 4 zone. from memory Electrovert used to do a small 5 zone with pin chain - Infraflow 500 or something. To be fair, even small one line CEMs usually have a decent oven as you need to be a

Although if you do many double sided boards you will want to avoid having to constantly fit boards with unreflowed components on into jigs, as there is plently of opportunity for defects. It's fine on the odd board, but doing it a lot is something t

The L Version is slightly bigger PCB handling capability. However, it's relative to Juki, not to other manufacturers. We have found that the extra large board Juki's are similar to our standard Yamahas. Don't know about the 760, but the 2060L is 41

Also, get your PCB suppliers to send you BBT failures that they would usually throw in the bin. In addition to print testing you and use them for profiling. We use a sticky film for print testing, then wipe, peel off and throw in the bin.

Hi Diego, Yes, we use a low tack Polyethylene tape, 300mm wide in reels of 250m. It's about 75 micrometers/ 0.075mm / 0.003", although we are looking at going down to about 0.06. Not all boards go through SPI, some just go through 2D - depends on
