The spec for all PCB suppliers is "solder mask over bare copper using LPI on external layers (green)". The flux we use is No clean 270WR flux (AIM). As far as process parameters, like I mentioned before, same parameters for several suppliers, only on

Your specification for all PCB suppliers of 'solder mask over bare copper using LPI on external layers (green)' is broad and open to the use of material from many possible LPI suppliers by your board fabricator. In at least one case, it appears that

You may need a glue despinser if you populate bottom side then wave. maybe a board deatacker at front of the line how about a multifunction pick and place machine so you can process all parts out there. we cleaned our stencils for years then we got a

Hi all, I have a question regarding some wave pallets having metallic traces of Titanium. The solder mask is blistering in some locations on the PCB and I am wondering if this Titaniumn may have an influence by incresing locally the temp. Also we ar

thk you very much for your fast answers. And yes, I am suspecting the same things also. The problem is to convince the PCB supplier that is his fault. A big fight all the time. SO, i will double check everything you said, and I willl come back with r

Hi If you mean your PCB stayed in the Reflow oven more than the reflow time required for the solder paste specs then I suggest to throw away the board because it would lead over heated solder joints all over the board. Think what could happen to an

Certain packages will always be out 90 degrees or so when a program is first ran on mydata. Is there a way to automatically adjust rotations for mydata packages when generated with circuitcam? Is there a location where we can adjust the angles circui

Hello, Has anyone dealt with the process of listing the substances on their electronic products due to REACH? I'm trying to find out if there is a way to globally calculate the area ratio of all the apertures on a solder paste stencil so I can calcu

The challenge you will have with ProWorks is it doesn't understand electronics. To create a dynamic legend (parts list) based on ODB++ or CAD import probably won't be easily created. Understanding components and seeing the CAD data related and sort

Hello, maybe not exactly good place for that kind of question - if so, please forgive me :) we are try to find a solution to seal (improve) the connection of our pipes with 8 Bar pressure - but without dissassembling them (with production running a
