Hola Beto Here we use this one CAB MAESTRO 3E it's ok does the job well and both blades can take a beating before need to change them. http://www.cab.de/en/electronics/pcb-separators/maestro-3e/ Saludos Beto

Samsung SM421/F Optimized Feeder List

I just noticed that under the print utility you can in fact Print To File, (disregard my earlier note about needing .pdf print driver) so this would give you an ascii ouput of the optimized feeder list. However, you still have to do it at the machine

Lenny send me some .opt and .pcb files with the original Altium or CSV file and your generated SSA file and I will reverse it out for you. It should take me only a little time. My email is on my webpage http://members.iinet.net.au/~sarason/ saraso

PoP parts

Opens are on the device to the PCB - mainly on the edges, that makes me think I get some kind of warping,but even if I bake parts and boards doesn't help. We also tried different reflow profiles - same results. I hear that some people use dip fluxers

Soldering to a nickel plated battery terminal

Electronics Forum | Mon Apr 21 16:38:45 EDT 2014 | barryg

Hello all. We have been having some problems soldering to what we believe is a nickel plated spring steel battery terminal to a PCB. We have tried scrapping , then tinning, dipping and still have problems. Are there any special fluxes or pre-treats t

0201 (0603) stencil spec

Electronics Forum | Wed May 07 08:16:58 EDT 2014 | emeto

It really depends on pad design and other component on the PCB. Most of the time I run 0201s I have microBGAs on the board and usually print 3mil. Reduction will depend on the paste. For leaded paste you will have reduction (about 10% or so).For Lea

Etch strain gauge in copper layer to measure deformations during press process [How to?]

Electronics Forum | Thu May 15 09:55:16 EDT 2014 | julianf

Tmo, Thanks for your reply. It gives good advise about how to perform tests. The type of strain gauges that I want to design are inside the PCB at various layers and I want to read the data during the press step. Do you know if these prefabricated

Mechanical Delamination at de-panel

Electronics Forum | Tue Jun 03 10:28:09 EDT 2014 | swag

Incoming inspection: Look for flaws and measure position of v-score as well as depth. If v-scored on both sides of panel, make sure v-scores are in alignment. Follow the PCB thru all processes inspecting after each stage of processing, especially

Solder mask peel from traces, post wave solder. Etchant residue?

Electronics Forum | Sun Jun 29 07:31:03 EDT 2014 | vitrost

Hi, We had experienced very similar issue on boards of a certain PCB manufacturer. Field experiments showed that the solder mask of this manufacturer is prone to swelling and peeling after it was in contact with our water-based flux. When you switc

Reflow of large monoblock ceramic filters thermal shock?

Electronics Forum | Fri Jun 06 06:11:18 EDT 2014 | paulg

I have a large monoblock ceramic filter on a PTFE based pcb material. The filter has a metal casing soldered onto the ceramic filter. I am concerned that if the heating rate is to rapid, then thermal shock / differential expansion could cause the fil
