Takt time (without a google search) is the rate (amount of time per pc.) at which stuff gets made on an assembly line, a workcell, a hi-speed SMT line, CNC machine cell, etc.... Takt time is governed by the gate (the slowest person, machine, etc. in

I'm not entirely sure that is accurate. The only people who want small 'desktop' machines are hobbyists/labs who are unable to accept the costs and time constraints placed upon them by a subcontractor and think they can do better themselves. Standalo

So lots of quotes and research later we have eliminated a few added a few to our choices lol. So it looks like we will be doing a decent volume now (due to our other board supplier letting us down as well). Roughly 4-5 million leds/connectors per mon

Hi Casey, I accept your BOLD Rework challenge. Considering you did not say what the TEST was. Let's base it on speed, thermal uniformity, and process repeatability. I have sample boards that I will take to APEX with Back to Back BGAs. Does anyone wa

ECD is working on some tools in the area of determining the Ideal or most Robust Profile, for a given paste, oven configuration and conveyor speed. Translation of this "most robust profile" into actual oven setting requires more knowledge about the

Here are some: Printing Speed : 2.5 ips (inch per sec) Stencil Thickness: 10 - 12 mil but the latter is the best. Dots sizes: u can get that from the Forum Archive...I used Dave F's dot sizes recommendation...they are good! Squeegee Blade : use met

Excessive bridging on SOICW-20, -16, SOIC-8, -14,-16. I've got a board, 4" x 6" w/ SOICs on bottom-side for wave solder. I've checked topside board temp for flux activation, wave height, wave surface with the glass check-plate going from 1" to 2" spa

Well, I'm going to assume you: * Have a nichel barrier between the copper on your board and the gold / solder solution * Use a lead / tin near euthectic solder If so, I pick "C" - It doesn't matter. When concerned about copper tin intermetallics, t

Hello once again! I am having a problem with a 24 pin connector bridging on the wave. We use very similar connectors on other PCB with zero problems. This connector bridges in the same place on the same pins. It forms like a little block of four

Mike, we use carrier's as a matter of course on all wave products, it let's us keep the conveyor width the same all the time so speed's up change overs and eleimiates one more thing that can be set wrong. The main aim of the exercise is to be able
