For upcoming trial installations, I need 25 Vinduino printed circuit boards. Not a sufficient enough quantity for cost effective outsourcing of assembly. The new version of the Vinduino board has a good number of SMD components, and after building the...
I've now had a go at using some solder paste and heating it to the required temperature using hot air.Turned out fairly neat. I did have trouble working out what temperature worked though. The resister was done with air at full blast and it almost got...
I have been spending what feels like way too much time preparing the vacuum plates. Overnight in vinegar did remove all of the mill scale. I do not have a lathe though so I could not do faceing to get a good sealing surface. Instead...
The board has been assembled to test the circuit's functionality. Zigbee module was mounted on the board right after DAC verification. The most challenging part was soldering the DAC chip and then, a bit easier was USB-C soldering. Quick examination...
Eventually I submit one product for Tindie.com (at this moment, I am not sure it will be admitted or not..) and it is a kit requires full assembly and I guess relatively good soldering skill and experience is required. (I think most of hackaday.com people...
putting the components on the pcb, grouped by function - power is firstand temporarily mount the power-boost pcb (to ease removal in the worst case) - looks ugly, but gets the job done...the two wires connect to the LiPo Battery - in the final assembly...
Required tools: Aluminium can.CNC.Sanding paper.Iron. Preparing an aluminium sheet for the stencil. The instruction for cut aluminium can. Cut the top and bottom of the can. Using the Iron straighten the sheet. Then cut the sheet with dimensions 100x50mm....
After receiving my new re-designed PCBs for #4chord MIDI - which is a real world example of putting this project here into reality (and pictures of that are now in the gallery), I thought I'll get familiar with the whole subject of solder paste stencils....
Last time we did a test to see if solder resist film can be laser engraved, see https://hackaday.io/project/191904-laser4diy/log/221159-solder-mask-laser-etchingThat looked quite promising, so we went one step further and tried to put a solder resist...
I have been thinking about how to reliably solder the surface-mount pin headers to the TinyFPGA BX module for some time now. I think I've come across a solution.Solder on the 14-pin outer/through-hole connectors. It’s important that they be soldered...
I got this tip from someone else when I had to assemble my first 0201 board. It seems a bit weird at first glance, but it works very well! The Idea Your solder might come in paste form, but it doesn't have to be in that state when you place the components....
