5. Electronics production¶

Worked on electronics for the first time in my life and it’s a very interesting challenge.

Machine:¶

The Milling Machine in Techworks-Amman is:¶

Roland SRM-20¶

Working Envelope: 203 (X) x 152 (Y) x 60 (Z) mm

Spindle Rotation Speed: Range 3,000 – 7,000 rpm

Softwares:¶

Fab modules

Tutorials¶

Fabmodules Tutorials

Materials:¶

Material used for PCB board is Copper on epoxy glass grade FR4

Safety:¶

Safety measures to be considered when operating the machine

Group Assignment¶

Opening mods platform and choosing required machine and operation

Importing the png file and defining operating parameters for traces

Importing the png file and defining operating parameters for outline

Saving changes made for the test part

Preparing the board for installing on the machines

Setting the origin and Z zero

Tools used for milling the board, for traces we used 1/64” Flat Endmill (Photo for tool packaging shows it’s Ball Nose Endmill) and for outline we used 1/32” Flat Endmill (Photo for tool packaging shows it’s Ball Nose Endmill)

Loading rml code file to machine control

Cut part on machine before removing, and Final board after removing from machine
