A solder mask prevents molten lead from sticking to unintended metals during PCB soldering operations, ensuring no unintentional shorts are created. Chemical reactions are important for manufacturing PCBs, including using an acid mask to define electrical traces and a solder mask to expose only connection points. Mass production uses solder mask films, and wave soldering […]
This text explains different types of solder joints used to join metal pieces together, including butt, angle, edge, lap, and T-joints. Each joint has different strengths and uses, and the variation used depends on the thickness of the metal and the required strength of the joint. A solder joint is used to join two pieces […]
Solder paste is a mixture of fusible metal alloy and flux used to hold components in place before soldering. It is classified by the size of the metal balls and can be obtained in different alloys. It can be applied using screen printing or other methods and acts as an adhesive. Solder paste is a […]
Solder wick is a copper braid used by electronics repair technicians to remove unwanted solder. It comes in standard and fluxed types and must be disposed of as hazardous waste. Experienced technicians use it with a desoldering tool to offset the expense and cleanly remove residue. Common problems include old copper braid, too little heat, […]
