Questions

PCB functional testing is a process where a printed circuit board (PCB) assembly is tested for its intended operation. It ensures that all components and circuits on the PCB work correctly together as designed.

Lead-Free Solder: Environmental friendly, commonly tin-copper or tin-silver-copper. Leaded Solder: Contains tin and lead, known for ease of use but less environmentally friendly. Silver Solder: Higher melting point, used for stronger joints.

SMT stencil refers to any stencil used in surface mount technology assembly. A laser stencil specifically is cut with a laser, offering high precision for fine-pitch components.

A stencil image is a visual pattern or design cut out from a stencil material, used for applying paint, ink, solder paste, or other substances through the cut-out areas to reproduce the design on an underlying surface.

A stencil file is a digital representation of a PCB stencil, containing the design of the apertures or holes that correspond to the pads on a PCB. It guides the manufacturing of the physical stencil.

Higher Unit Costs: Lower economies of scale can lead to higher per-unit costs. Resource Intensity: More hands-on management and oversight required for diverse, small-batch production. Supplier Challenges: Securing cost-effective materials and components in smaller quantities can be challenging.

FR-4 is the most commonly used low-cost PCB material, known for its good electrical properties, durability, and flame resistance. Other affordable options include CEM-1 and phenolic paper laminate for less demanding applications.

Varies by manufacturer and application; standard sizes can go up to 18x24 inches, with most fitting within smaller dimensions for standard processes.

High Volume: Ideal for mass-market products, offering cost benefits but requires significant design and testing investment. Low Volume: Suited for prototypes and small runs, providing flexibility and easy design adjustments at a higher cost per unit.

Combines automation's speed with human flexibility. Improves efficiency and quality control. Adapts easily to production changes and complex designs.
