Ruth's sister 60x80mm Flexible Single-Side FR4 Breadboard Prototype Board

Ruth's sister 60x80mm Flexible Breadboard

This thin FR4 laminate board measures 60 by 80 millimetres and provides a 2.54 millimetre hole pitch for standard component spacing. The flexible substrate can be folded without deformation and cut to custom shapes for unique layouts. It suits hobbyists and engineers building one-off prototypes or experimental circuits. The single-sided copper pads accept through-hole parts and simplify soldering with a tin-plated finish.

Check component lead diameter and board thickness

Verify that your component leads fit the 1.0 millimetre aperture with its stated tolerance before ordering. The board thickness is 0.4 millimetres, so ensure your enclosure or mounting method accommodates this slim profile. Because the material is flexible, plan for mechanical support if the assembly will experience vibration or repeated flexing. No mounting holes are included in the design.

Thermals noise and power draw in normal use

The board itself draws no power and produces no noise, as it is a passive prototyping substrate. Thermal performance depends entirely on the components you populate and the current they carry. The FR4 glass-fibre base resists pad lift during soldering but does not act as a heatsink. For high-power circuits, add external cooling or copper pours on your custom layout.
