ROHS Compliant Printed Circuit Board

A Rohs compliant pcb is one that does not use any lead in the manufacturing process or soldering. Rohs is a regulation for the use of lead in various products, and has slowly become a standard in printed circuit board manufacturing.

Metal Core PCB

Metal core printed circuit boards are used when thermal losses or output of the components needs to be managed, since the core aids in dispersing and acting as a heat sink.

In this kind of pcb, a piece or plate of metal is laminated inside the regular insulating substrate, where the tracks are etched and components soldered.

FR4 Printed Circuit Board

FR4 is a flame retardant used in circuit board manufacturing. It is used to provide protection against fire that could start due to short circuits, sparks or other component failure.
