Common electronic components repairs and hand soldering techniques

These stations send hot air through the device to warm solder for removal or resoldering. An all-in-one hot air rework station can meet these needs without requiring multiple devices. Hot air rework stations come in many sizes to accommodate different printed circuit board sizes.

Surface-mount technology (SMT) is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). In industry, this approach has largely replaced the through-hole technology construction method of fitting components, in large part because SMT allows for increased manufacturing automation which reduces cost and improves quality.

A surface-mount device or SMD is an electronic device for which the components are mounted or placed directly onto the surface of the PCB.

RoHS is often referred to as the "lead-free" directive, but it restricts the use of six substances: lead, mercury, cadmium, chromium VI (also known as hexavalent chromium), and PBB and PBDE (flame retardants used in some plastics). Relating to electrical and electronic assemblies and components in which the lead (Pb) level in any of the raw materials and the end product is less than or equal to 0.1% by weight and that also meet the Pb-free requirements/definitions adopted by the RoHS Directive 2002/95/EC.
