Probably you’re following Dave’s eevblog. He regularly publishes great stuff for electronics engineers and enthusiasts. Following video might be useful for someone who deals with small SMD parts like LGA. Soldering those might be tough, but there is always a way out of the situation. This video demonstrates how to solder three-axis accelerometer on to prototyping board in dead bug style. By following this technique, you can solder almost any SMD chip that is meant for re-flow soldering.
Well this sound amazing and scary. Everyone knows that printer toner usually is transferred with special glossy paper and iron, but printing directly… anyway fact is that it is possible and gives amazing results. Author claims and proves that he was able to print 2mill traces what means four traces between two DIP pins. There isn’t any information about how it’s done as other people claim that printers modified as flat doesn’t give even close results. Take a look for more photos in gallery.
You have to prepare many multi-platform eagle designs for manufacture, but you have no ideas what to do about it? Well, there are many ways to turn an eagle design into an actual PCB. One of the best ways is to save the eagle designs as industry-standard gerber files, where you can use the gerbers files to order a single prototype or in a full panel. For your information, the toner transfer is the favorite choice of beginners to make a PCB, as the total investment in materials is minimal comparing with other methods. Most of the PCBs are made with the photo-resist process, since the photo process makes nice boards, but it requires a bit of equipments. While some of the board manufactures, such as the olimex, can be used to make PCBs directly from eagle .brd files. Olimex requires a minimum order of one eurocard-sized PCB (100mmx160mm). Here’s the simple process of Eagle Designs: Firstly, you’ll need to prepare the design; Secondly, create grebes and generic files that accepted by any PCB fab house; Thirdly, remember to verify the gerbers; Lastly, send the design for production! The best and cheapest option you can get is to submit gerber…
If you like designing PCB’s with Eagle CAD software this Eagle library may save you tons of time. It has many great footprints that are popular but not included in standard Eagle library like RGB through-hole LED, 16×2 LCD, Relays, RCA Jack, 3.5mm Audio Jack and more. Check out full list which is updating time to time. Also if you’re new to Eagle don’t forget to check Eagle Tutorials for fast start.
Probably you have read about our PCB etcher on our site. We planed to make it fully automatic with heater, bubble machine and thermostat. But fact is that it wasn’t finished. But we are actively using it with aquarium heater only and manual mixing :). If you are looking for something similar that has a bubble machine installed you should see YourITronics brand new PCB etcher with aquarium pump and heater. They use a bubble machine that speeds up etching process and you don’t have to mix solution. The tank is made of plexiglas and holds 1.5L of liquid. All together with pump, heater and other materials etcher costed about $41 – this is much cheaper than buying from store. This tool is a must have along with UV exposure unit.
If you are just starting in electronics this nice tutorial may save you tons of time. Yourtronics prepared a nice tutorial on how to make good quality PCB by using Photo Etching Method where board image is transferred during UV exposure. For this you will need an Ink-Jet printer for printing mask on transparent film, UV exposure box which can be made at home, several chemicals (Developer, Ferric Chloride, and Acetone).
