It used to be pretty straight forward to assign a net to a hidden pin of a component using the right-click property menus. However, this function has been relocated to…
The scope of the OpenRISC project is so extensive that it covers wild range of areas including processor architecture, implementation with register transfer language, simulation tool, synthesis tool, and tool-chain…
I talked about soldering small surface mount LED in my previous posts by using DIY reflow oven. Today I would like to show you how to rework similar LED, which is,…
The first impression of the Ricoh Theta 360 Degree Spherical Panorama Camera is its odd appearance — to me it feels like a bar of chocolate wafer. The dual lens reminds me…
First of all, please watch the video below to find out how everything was done on my work bench. A recent project requires soldering 600+ tiny LEDs on long narrow…
I am working on a DIY PCB project that requires mounting three PICOR PI3301 Power regulators. Unfortunately, the PI3301 comes with a high density 123-pin LGA footprint in a 10mm…
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…
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. [youtube=”http://youtu.be/AXBflP_4fdQ”] I talked about DIY…
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…
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…
