For me it was the 1.0mm nozzle, if we're talking mini-MELF here. Also, slowing the turret speed helps. Had mine at 30%. Results vary if placing on paste vs. glue. Paste is better. Still, the std. 1.0mm nozzle is where near as good as with the MELF no

Hi Serge, First of all: "i HAVE to buy"...? Sounds like someone is twisting your arm to buy a piece of iron you're not really enthousiastic about... But on a serious note: I've been comparing some machinery myself (also with Pana and Siemens) and I

Fuji is the best, but there are other alternatives besides Quad. If you really want to look at Fuji, take a peek at their XP142E series. With "Vision processing on the fly" and a "Mini Turret Head" with 12 placement nozzles it should fit your needs n

Rob, I am currently using a BGA-3000 from OK, which works fairly well. I did find that the customer support for the purchase of nozzles and stencils was very poor (overpriced and long lead times). I did find stencils for a good price through Mini

i have done this thousands of times. You are correct about no preheat, however it never seemed to be any issue for us. You do have to make sure that you do not expose any SMT comps. to the solder or they will become heat stressed/fractured. Connec

Thanks Real Chunks. We currently have an RPS opus selective solder machine that we plan on keeping. It is configured as a 3-nozzle (!) one-pump (!!) point selective solder machine w/ nitrogen preheat. Custom wet nozzles. We use lead free SN100C sold

| | Hello everyone, | | We found many cylindrical diodes missing during SMT process. Could someone tell us how to prevent this problem? Is it effective to change the shape of stencil apture or reduce fan speed in reflow oven? Thanks in advance. | |

Charles, I am using an Air-Vac PCBRM12 to selectively solder a 96 pin thru-hole connector onto an otherwise all SMT board. Cost is $8.6K plus about $300 per flow well (nozzle.) Went from a 6 minute cycle to hand solder the connector to 15 seconds o
