Welcome to a new Voltlog, today we’re going to be talking about the possibility of designing a pcb business card. So if you’re an electronics engineer who offers consulting services or even just an enthusiast and you would like to create a nice original and suggestive business card, stick around.
The idea of making a pcb business card is not new and there are many previous examples of pcb business cards, some people build them passive, others like to integrate a small battery some LEDs, maybe a microcontroller with NFC or a USB interface and generate some interaction with the user.
Maybe 7-8 years ago I first wanted to try this idea but back then, it was quite expensive to get PCBs professionally manufactured in China, first they were charging a setup fee which was usually $150 and then you would have the cost of the PCB which for 10 pcs 10 by 10cm was usually about 2-3$ per piece and then you would have the shipping cost which starting from something like $50 for the first kg via DHL. And all of this was for the standard 1.6mm FR4 with green solder mask and tin finish. If you wanted matte black soldermask and gold finish, there was an additional cost.
