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
