assembly software for JUKI

Electronics Forum | Sat Jul 06 19:49:41 EDT 2013 | sarason

My software can easily open a PCB CSV file so this is probably the easiest way for you to generate a file. The setups are remembered via a write to the registry, so you can go with a standard set of values to arrive at a very usable file without havi

THM Solder barrel fill issues on 93 mils board

Electronics Forum | Wed Aug 21 09:09:50 EDT 2013 | wcheew

I am having solder barrel fill issues on THM component, we follow, we follow IPC 610 E requirement. The barrel fill issues happen on signal & ground pin at connector & E-cap. I found out that most of the insufficient solder happen on the connector ag

through hole today

Electronics Forum | Mon Sep 09 16:29:56 EDT 2013 | gregp

Hi Everyone, I'm looking for some feedback about through hole assembly requirements today vs. yesteryear. As I see it, there are two main categories...legacy through hole and new through hole with mixed technology. The legacy stuff is older designs

Ion Chromatography Testing Standard

Electronics Forum | Thu Sep 26 15:28:16 EDT 2013 | joeherz

I know - A stimulating topic.... IPC-TM-650 2.3.28 method calls for a PCBA or PCB to be placed into a bag with solution, shake, analyze. Great. There is a method of doing this testing that focuses on a specific area of a PCB or a component where r

Expected pick and place precision for 0603 LEDs?

Electronics Forum | Tue Nov 12 17:11:32 EST 2013 | mondalaci

Hi Folks, I'm working on a LED display that is composed of multiple layers. What is interesting for the point of this discussion is the PCB layer and the light deflector layer on top of it. Please take a look at the related pictures at http://plus

what software is out there that will extract XY centroid from gerber data?

Electronics Forum | Sun Feb 16 11:14:07 EST 2014 | unisoft

As mentioned the ProntoGERBER-CONNECTION software from Unisoft ( http://www.unisoft-cim.com/gerber_connection.htm) does the Gerber to intelligent shapes (ref des, x/y center, rotation, p/n, etc.) function for over 25 years. If you wish I'm availab

what software is out there that will extract XY centroid from gerber data?

Electronics Forum | Mon Feb 24 12:41:18 EST 2014 | mi

Depending on what X-Y centroid / CAD data you need, there are different SW I've used to do the job. If you need PCB gerber "artwork" (rounds, rectangles, lines, squares,...geometric figures), you can use GraphicCode GC-Place & such - load the gerber

Lead free SAC solder paste on Sn63 HASL PCBs

Electronics Forum | Tue Jan 06 16:31:41 EST 2015 | jacklucas

In switching to lead free processing, we find ourselves having over 400 PCB part numbers with Sn63 HASL finish. And there is no hope of quickly purging inventory and getting our drawings changed to call out a lead free finish. I want to avoid having

PCB profiling

Electronics Forum | Mon Feb 16 10:33:58 EST 2015 | rgduval

Drilling a hole, and attaching the thermocouples underneath the part is the recommended way to profile for a BGA, unfortunately. It allows the best method of collecting specific data, including any thermal sinking/shadowing that the BGA creates. Ho

Questions you would ask if someone said they had a 3D printer for professional multi-layer PCBs?

Electronics Forum | Thu Feb 26 08:44:38 EST 2015 | spoiltforchoice

...Unless you could dispense a fine glassfibre mesh in much the same way a 3D printer extrudes plastic filament and then spray epoxy over the top. It would be remiss to 2nd guess what compounds physical chemists can come up with for such a project. E
