The Purpose of the PresentationSteps of Karelino prototype
manufacturingKarelino Testing & Debugging
Karelino Design
We use single sided PCB We need next drawings
Schematic Copper Bottom Silkscreen
3D views could be very helpful

PCB manufacturing method & materials Method = Transfer Toner System Materials = Pulsar kit (PCB Fab-In-A-
Box) http://www.pcbfx.com/
We print the copper layer on paper using a laser printer
We prepare the single sided board using a sandpaper
We clean the surface with a cloth
We use a laminator to transfer the toner from paper to board
We remove the paper using water
The copper layer is transferred to the board
We use green foil (from Pulsar) to seal the toner
We remove easily the green foil
Toner before and after sealing
We are etching the board using ammonium persulfate
The uncovered copper was removed (etched)
We remove the toner from the board using thinner
We drill the holes
We test the traces for continuity and short circuits
We use a soldering iron station to solder the components Hot Air Gun Soldering (Hot) Iron
We first solder the jumper wires
We add the components and we solder them (SMD first & THD last) – A magnifier is very helpful

Testing & Debugging
We had 2 types of mistakes: Design Mistakes ->
Guilty Person = Mr. Mihai Agape Manufacturing Mistakes ->
Guilty Person = Who knows?
Test your attention to detailWhat mistakes can you identify? http://1drv.ms/1jet3ci
Two resistors are placed wrongWe identified the mistakes and repaired
We found the mistakes and we corrected
