pcb-name-card

My name or business card that is on a Printed Circuit Board (PCB). Comes with an white LED, UV LED and a ruler. Not forgetting a QR code containing my contact details in Vcard format.

Screen

The lastest iteration of my name card is now in white.

I gave a talk on my name card, slides available in the picture link below.

My slides on slideshare

###PCB Design software and addons/references used

  1. Eagle 7.3.0: I use Standard but Light should still be able to open/modify the files.
  2. Modified CR2032 library based on here
  3. Elecrow Design Rule Check for 2 layers (in repo as Elecrow_2-layer_eagle_rule.dru)
  4. Elecrow Gerber Generater 2-layer board (in repo as Elecrow_Gerber_Generater_DrillAlign.cam)
  5. QR code generated from here

###Schematic drawings

Images are exported from Eagle at 600dpi.

###Bill of Materials (BOM) for components only

Screen
Components in their raw form

Screen Components still in their original packets from different suppliers.

Assume minimum order 10 pieces, cost in Singapore dollars. There are additional savings if I order more say 50 units but the savings are still small. Delivery for BOM not included.

The BOM is available in the odt spreadsheets in this repo.

###PCB fabrication

PCB fabrication is currently done by Elecrow (10-pieces-link) or (50-pieces-link) based on the following settings. Remember to consult the order submission specifications at the bottom of the previous link before submitting. Use the provided Gerber generator to produce the Gerber files.

####My Fabrication Settings:

  1. Layer: 2
  2. PCB Thickness: 0.6mm
  3. Copper Weight : 1oz 35um (NA for 50 pieces)
  4. PCB Size : 10cm Max * 10cm Max (or 50cm2 for 50 pieces)
  5. PCB Color : Blue or Black
  6. Surface Finish: ENIG
  7. PCB Stencil : NO Stencil
  8. Lead time : Shipped in 4 to 7 days (NA for 50 pieces)
  9. Panelizing : Single PCB with milling

###PCB Cost including delivery Assume US$1 = SG$1.3

####Unit cost for 10 PCBs only Total PCB Cost: US$30.80 + US$16.17 (DHL) = US$46.97
Individual PCB Cost: (US$46.97 * 1.3) / 10 = SG$6.10

####Unit cost for 50 PCBs only Total PCB Cost: US$62.47 + US$18.81 (DHL) = US$81.28
Individual PCB Cost: (US$81.28 * 1.3) / 50 = SG$2.11

###Total Unit cost (SGD$) with components

Pieces Young Blue Formal Black
10 $15.53 $17.19
50 $10.53 $12.26
