$100K for this entire line. We are thinking of getting a Chinese made reflow oven that looks pretty good at $25K. Also, we need to deposit solder using a dispenser as stencil printing will be reserved only for higher volume boards. It will not be pra

I, too, have finished qualifying the Amtech paste for a dispensing application. We will be experimenting with the component soldering/stencil printing next. The stuff has proven to provide the best of both the no-clean/low solids and water washable

We are looking at a specialized method of direct soldering ceramic circuit modules (maybe 40mm square) to a mother board with solder joints on only 2 of the 4 sides. These modules would be oriented horizontally, or mezzanine like, to the mother board

Jim: I have limited knowledge, but here's what I know: 1. Yes, it's a standard process. In today's SMTNet, it's rarely mentioned, and few people reply to postings. 2. Nope. It's a "specialty" piece of equipment for most CEM's. Depending on you

Thank you Pavel for your interesting. Speaking on tact time ( machine speed per Board ), our Universal machines are too quick thank DEK machine, that's why I am thinking to add another machine in Glue process. FYI, we are working on Satellite receive

Dear ERhard.Our placer are Universal Genesis machines and the screen printer is DEK Horizon 02i . for Maian board the tact time in the placer is about 14 Sec and the printer is about 22 Sec. Means there is a big waste time . for Front pannel we are u

This solution is not as complicated as you might have thought. T-conveyor connected machines are widely used for applications requiring high material deposition throughput. This solution is made of: 1. Two independent screen printers 2. Two line loa

But his placement machine time was 13-14 seconds. That's the goal. "Our placer are Universal Genesis machines and the screen printer is DEK Horizon 02i . for Maian board the tact time in the placer is about 14 Sec and the printer is about 22 Sec.

We have a job that has through hole components on the top, and one 44 pin j leaded PLCC on the bottom. Presently we put the through hole parts in, run it throught the wave, dispense paste on the PLCC pads, and then apply hot air. Someone suggested we

Shy, You mentioned that you are using "dog bone" apertures for your chip components? It doesn't make sense to me. I thought that the "dog bone" was used for fine pitch devices, to keep the solder away from the center and avoid bridging. It doesn't
