Semiprofessional PCB production - data processing - Electrical schematic (OrCAD, EAGLE)
Print (creation) film (the original, cliche) - On a laser printer (special foil) - On an inkjet printer (special foil) - On the common printer it is not possible to create a rich black color The quality of the film is given by: - consistency layer film - Transparency film - Intensity of black
Preparation of cuprextite boards - select the size and shearing of the cuprextite boards - Filing, chamfering - Application of a photosensitive layer (brush, on centrifuge) - Cured in a furnace
Drilling fixation holes (double-sided PCB) PCB exposure (photosensitive layer)
Calling in the developer Etching Developer-NaOH Countersink for copper
Drilling holes-drill for PCB, PCB description
1. Describe the preparation of the cuprextite plates 2. Write what is produced in the film (the original, cliche) 3. Write what is given to the quality of the film
1. Write what solution is used when creating the PCB 2. Write what solution is used for etching PCB
