leadfree processes

What are leaded and leadfree processes?

What are leaded and leadfree processes? Leaded solder typically consists primarily of tin-lead (Sn-Pb) alloys, such as the classic Sn63/Pb37 (63% tin, 37% lead), which has a low melting point

encapsulation process

Semiconductor encapsulation process and development

The encapsulation process, also known as the packaging process, involves the secure enclosure of semiconductor chips using specific materials. This provides effective defence against environmental degradation, ensuring stable chip operation.
