PRINTED CIRCUIT BOARDS 2 Preparation of cuprextite boards • - select the size and shearing of cuprextite boards • - filing, chamfering • - drill holes for mounting • - definition of space for components
PRINTED CIRCUIT BOARDS 2 Selection of components (dimensions) for the connection • Catalogues • Internet
PRINTED CIRCUIT BOARDS 2 • PCB design of the components (TOP) manually on paper rasterized (2,54x2,54) • - without cooling (or earth) • - of cooling (or earth)
PRINTED CIRCUIT BOARDS 2 PCB from copper (BOTTOM) • - without cooling (or earth) • - of cooling (or earth)
PRINTED CIRCUIT BOARDS 2 Production of custom board (PCB) • Drawing on the board an alcohol marker • etching the counterbore • PCB treatment (washing, drying, coating resin varnish) • drilling bores • control PCB (visually, short-circuit measurement) • description for the orientation TOP
