Frequently Asked
Questions

Manual Soldering: Using a soldering iron for individual components. Reflow Soldering: Applying solder paste and heating the entire board to melt the paste, used for SMT components. Wave Soldering: Passing the PCB over a wave of molten solder, primarily for through-hole components.

Solder creates a secure and conductive connection between electronic components and the PCB, ensuring the circuit functions as intended by facilitating electrical continuity.

Clean the surfaces to be soldered. Apply flux to remove oxides and improve wetting. Heat the joint with a soldering iron. Apply solder directly to the joint, not the iron tip. Remove the iron and allow the joint to cool naturally.

Manual Soldering: For prototypes or repairs. Reflow Soldering: For surface-mount components. Wave Soldering: For through-hole and bulk components.

EOL testing differs from other methods by being the conclusive assessment performed after all manufacturing processes are completed, focusing on verifying the final product's functionality and compliance with specifications, unlike specific component or assembly checks done earlier.

To package a PCB, first clean and inspect it, then place it in an anti-static bag. Wrap it with bubble wrap or foam for shock absorption, and secure it in a sturdy box with cushioning materials. Finally, seal the box and label it with handling instructions and ESD warnings.

Shipping methods for PCBs include standard postal services, express courier services (like FedEx, UPS, DHL), and freight services for larger shipments. The choice depends on the urgency, volume, and budget.

Rapid prototyping is a broader concept that includes 3D printing among other techniques like CNC machining and injection molding for creating prototypes quickly.

Tracing a PCB circuit involves carefully examining and mapping out the connections and components on a board to understand its electrical flow and functionality.

PCB reverse engineering is the process of analyzing a physical PCB to recreate its design. Preventing it involves using encryption, proprietary components, and complex circuit designs.
