    PCB Mounting Hole Padstacks

    Hi all, Just wondering if anybody could refer me to a formal standard or similar for the padstack data of mounting holes? Tom Hausherr has provided some useful, but unreferenced info on his blog - http://blogs.mentor.com/tom-hausherr/blog/tag/pcb-mounting-holes/ - and I wonder where it might...

    Software for circuit drawings/design

    As another option, Promis-e might be worth considering. It comes with pre-installed blocks, and in various flavours to suit your requirements. Not endorsing it; I haven't used it but the folks at my previous place of work were very pleased with it. It also integrates with AutoCAD and provides...

    Question On Responsibilities:

    To me, this has much less to do with 'legal responsibility' and much more to do with, as others have alluded to, "how to win friends and influence people!" The very fact that a 'responsible entity' is being sought rings alarm bells. Of course, I don't know the individuals involved, and you...

    assembly method for LCD in a handheld device

    I think that the method you choose will be entirely independent of the alignment that you can achieve. It surely all depends on tolerance? You will only achieve the desired, or consistent alignment if you have appropriate tolerances. Regardless of how you assemble it, the weakest link will be...

    Personal (work related) notes

    @dik Thanks for your comments. Perhaps I didn't make myself clear; what I meant by these notes are supplementary to project documentation, is that their content is not required for the project; they are over and above project documentation and have no real reason to be included. There are no...

    Personal (work related) notes

    Hi all, Having searched the forum for posts of a similar nature, I've found nothing quite relevant to the topic. I keep an electronic notebook (Evernote-based for those who are familiar or interested) to aid my productivity; manage actions, referencing hard copy notes already filed, log...

    Connector Help

    Not sure I understand the application, but I have used welding connectors for medium and high cutters applications, such as the 'Dinse' range. I would recommend a look onto them.

    Gold Embrittlement in solder joints

    Status, extracting the gold on such a scale would take more than a long time and is not practical. One would be better off creating a new joint. I am not familiar with IPC 610, and given you are on a course for such; would it not be wiser to ask your trainer?

    Gold Embrittlement in solder joints

    Status, take a look at this document that I posted earlier: http://www.sem-lab.com/GoldEmbrittlementofSolderJoints.pdf Read the article, look at the pictures and then you should grasp the magnitude and process by which it occurs. If you have any questions afterwards, please come back. "If...

    CE Wiring

    Being in the EU, it is something I am familiar with, though do not encounter very often with respect to consumer goods. I have only thus far certified equipments for use within explosive atmospheres which requires a CE mark. Most consultancies will offer you a free consultation. No answer or...

    CE Wiring

    Lionel, perhaps you are thinking of the WEEE directive, Waste of Electrical and Electronic Equipment?

    CE Wiring

    You [u]should[/] come across the RoHS directive, as well as the Low Voltage directive and the WEEE directive, just to name a few which deals with the waste of electrical and electronic equipment. I say should, because these will form part of your declaration of conformity - if you follow the...

    Gold Embrittlement in solder joints

    "That was interesting to read but it all seem to be at a microscopic level" Gold embrittlement on a 10 inch wide solder joint (if they exist) would be the same gold embrittlement that exists in your own solder joint. If you want to disregard the microscopic level, then what you might come...
