Understanding OSP PCB Surface Finish OSP is a chemical coating applied to the exposed copper pads on a PCB after the etching and plating processes. The organic compounds in OSP form a protective layer that prevents the copper from oxidizing and maintains its solderability for a limited period. Composition of Read more…
Understanding Surface Finishes in PCB Manufacturing Surface finishes are critical in PCB manufacturing as they protect the exposed copper pads from oxidation and contamination. They also enhance the solderability of the pads, allowing for proper bonding between the PCB and the electronic components during the assembly process. There are various Read more…
Understanding Solder and Its Composition Solder is an alloy, typically composed of tin (Sn) and lead (Pb), although lead-free alternatives are increasingly common due to environmental and health concerns. The specific composition of solder can vary depending on the intended application and desired properties. Common Types of Solder Lead-based Solder: Read more…
Composition of Solder Paste Solder paste is made up of two main ingredients: Solder alloy powder Flux medium Solder Alloy Powder The solder alloy powder makes up 80-90% of the paste by weight. It consists of tiny spherical particles of solder, typically a tin-lead (SnPb) alloy or lead-free alloy such Read more…
