QFN (Quad Flat No-lead) is another term for MLF (Who knows.) Check in the files for the MLF library. It covers several 0.5mm pitch parts. Microsuffer...
There are probably quite a few transformers with different footprints that can do 220v to 12v a.c. 0.5VA. Do you know the part number and manufacturer for...
I've got the footprint from one of our members (kudos, Ovidiu), and at the same time I've made one myself. Both are in the file EuroCard.lld (uploaded into...
I had earlier mentioned the MLF library in response, but the part is a QFP, not QFN. The correct library for that is the Demo library QUAD.LLB. Oops....
Thanks your a good man. Jim ________________________________ From: microsuffer <microsuffer@...> To: OrCADexchange@yahoogroups.com Sent: Saturday, May 2,...
None of those would fit either too small or too large . Here is one I built. How does it look to you. I printed it out and the part fits perfectly. .08MM lead...
Non text portion removed so I didn't get to see the result. However, in QUAD there is the QUAD.80M/44/WG12.00 which matches the dimensions on the data sheet....
You are absolutely correct fits much better that the one I made. Thanks Jim www.soundlogicus.com Plasma THC-300 Serial Spindle Speed control ... From:...
... Thanks, nice calculator. I'm interesting about normal working current let's say for 20C temp rise and maximum current when the via will burn out. I...
First, you didn't mention which Polyfuse. Assuming a Littlefuse 2016-1.5, a part that will sustain 1.5A at 23C, the data sheet seems to say it will take 100K...
Poly fuses are very slow devices. If 3A were placed on the 1.5A poly fuse it would take about a second for it to open. The copper in the via is fast to heat...
Hello, Gud day everyone.. would like to know if anyone here happens to have a PCB template for Eagle system ETS-364 loadboard design. or worst case the...
... I know they are very slow but is there some better and cheap solution when burning fuses are not acceptable and electronic limiters are "complex" and...
So, you have a population of boards that have to be lived with. Drill out the via and put in a wire? And where is the fault current going? Is it a reasonable...
I have written beginners's tutorial for OrCAD schematics. http://referencedesigner.com/tutorials/orcad/orcad_01.php I am looking for members' feedback about...
Dear All Could you provide me with the layout footprint of 80-Lead Plastic Thin Quad Flatpack (PT) 12x12x1 mm Body, 1.0/0.10 mm Lead Form (TQFP) for PIC18F8722...
hi members I am electronic engineer.i am working in orcad for last three years and hope these groups are useful to share the knowledge of everyone Regards ...
Hi Ala', OrCAD Layout comes with a standard library called QUAD. It has eight (8) 80-pin footprints that look like QFP. They have different dimensions...
Hello, I'm looking for the layout file (.llb) of the SC70-5 package. I've been through most of the libraries I found here with no luck. Could you please let me...
Hi all... If I understand correctly, this group is not for Orcad/Allegro systems. I cannot use your libraries. If you put the footprints into a layout, I could...
Folks, What end-mill diameters fabs typically used for routing (milling) the outline of the PCB? I have a PCB with an inside angle. I don't want to make an...
