The “copper to drill hole” distance is an important rule for circuit board design, just like the “copper to copper” clearance. A PCB manufacturer usually announce their minimum allowable clearance…
Owning 3D printers with different nozzle diameters, I am able to give some first-hand experience on their advantage and disadvantage. Hope these could be helpful. FYI, my 0.4mm printer nozzle…
If you have read my previous post about how to extract useful data from INTE HEX32 format hex file, you are just one step away from being able to burn…
A big improvement of dsPIC33e series micro-controller from its predecessors is the re-mappable peripheral IO. This allows great flexibility for circuit board design, but also requires slightly more efforts to use…
First of all, let’s take a look at the video clip below (link) to find out how it is possible to reflow solder components without stencils. I talked about DIY your…
First of all, let’s check out how easy and sweet it is to remove the supportive raft from your 3D print. All you need to do is just to follow…
First of all, let’s see the video of the heated print bed in action! This table is built for Type A Machine 3D printer, but it should works for all…
My reflow oven in action! Although I can skillfully solder as small as 0.5mm pitch QFN package chip by hand (post, video), more and more space saving components appearing on the…
If you have read my “Designing bootloader for Microchip dsPIC33E/PIC24E micro-controller(2)” of this series, you should be able to extract all the necessary information from the hex file compiled by…
I sent out a new circuit board design to a PCB fab house last week, but was put on hold multiple times for the reason of “insufficient copper to copper…
