Perforated Phenolic Plate

So you finish your electronics projects, such as printed circuits. We know that designing a prototype or electronic project can be a complicated task if you do not have the necessary items to carry it out, so with us you it a phenolic plates of a face, two sided or perforated, ferric chloride, auto-adherable tracks, leaves thermal transfer or permanent ink markers so that your circuits are perfect.

Steren Model 155

Bakelite phenolic plate with copper, 4.5 cm x 4.5 cm, engraved and perforated with 164 orifices for components and 4 for fixing the plate. Ideal for projects or prototypes.
