Single sided PCB:

Single sided PCB is the simplest and most common type of PCB. It was the first device used for the interconnection and assembly of electronic components forming a coherent and functional operating system. The primary industry using these cards is the consumer electronics industry.

Double sided PCB:

The double-sided PCB is more complex than the single-sided PCB because it connects 2 faces of a circuit in 2 layers connected via PTH (Plated-Through Hole) which depends on the design

 

 Normes Details
Currently, we accept the following PCB file formats:

In a zip or rar folder:

_ Eagle file (.brd)

_ Sprint layout file (lay / lay6)

_ALtium file (.PcbDoc)

_Proteus file (.lyt / psdsprj)

_Adobe DXF file for Antennas.

_Gerber files (See in details)

 

In a zip or rar folder generate the following Gerber files with the                            RS-274-X format:

GBL: Bottom Layer

GBO: Bottom Overlay

GBP: Bottom paste Mask

GBS: Bottom Solder Mask

GKO: Keep Out layer

GTL: Top Layer

GTO: Top Overlay

GTS: TOP Solder Mask

DRL / DRD : Drill file

Minimum distance between track and via: 0.25 mm
Minimum distance between track and pad: 0.3 mm
Minimum distance between track and frame: 0.3 mm
Insulation between the circuit and the ground plane 0.3 mm
Maximum and minimum size of PCB boards PCB single sided : 30×40 cm²

PCB double sided : 22×30 cm²

 

 

 

Minimum dimensions for single / double sided PCB:  2x2cm²

Minimum thickness for a patch between 0.4 and 0.5 mm
Minimum distance between two via or two fixing holes 0.3mm
