The drag welding and dip welding processes offer different options for selective welding on PCBs, with drag welding suited for tight spaces and dip welding providing stable welding for short pins and small pads.
The development of lead-free regulations has a significant impact on PCB board assembly, with increasing concern about lead pollution and a focus on compliance with strict regulatory requirements for hazardous substance prohibition in electronics manufacturing.
Selecting appropriate process materials is essential for quality and efficiency in SMT patch processing, encompassing solder, flux, adhesive, and cleaning agents, which play critical roles in welding, bonding, and ensuring cleanliness post-soldering.

The SMT assembly process is closely related to each process step before soldering, including capital investment, PCB design, component solderability, assembly operations, flux selection, temperature/time control, solder, and crystal structure, with the most commonly used solder for wave soldering being eutectic tin-lead alloy. Temperature control and solder purity are essential for ensuring quality solder joints.
The speaker has completed circuitry and programming for a new project and is now designing a case. They have never designed a case before. The design is simple, an aluminium extrusion with switches and connectors. They have questions about attaching a display and finding a connector for the back panel.
