User Guide for a Lead-Free/
RoHS-compliant PCB assembly
- Printed Circuit Board/Circuit Card: Make sure to have your printed circuit board vendor fabricate boards for lead-free / RoHS compliance. Make sure the PCB board manufacturer uses materials that can withstand the additional heat and can make multiple passes through processing without problems.
- Components: Your Bill-of-Materials must specify only RoHS compliant parts. The components in your kit must all meet lead-free and RoHS standards.
- High-Temperature Considerations:
Even for RoHS-compliant components, some of them cannot sustain high temperature. Please make sure to notify us if any component is heat sensitive.
- Ball Grid Arrays: Ensure the solder balls of the BGA are lead-free type. Soldering a lead-based solder ball BGA at lead-free reflow temperatures will fail.
- Moisture Sensitivity: Ensure components are kept in RoHS compliant storage packaging to prevent moisture. If any unopened package exceeds the expiration date or is being opened, these components will need to be properly baked to remove the excess moisture before manufacturing.
By following these guidelines, you can ensure your printed circuit board assemblies are both RoHS-compliant and reliable.

What is a Printed Circuit Board Assembly (PCBA)?
Printed circuit board assembly, also called PCBA, is the process of soldering or assembling electronic parts to a printed circuit board (PCB).
What is Surface Mount Technology (SMT)?
Surface Mount Technology, or SMT, is a printed circuit board assembly process for SMD electronic components. SMD components do not have leads or legs. They are mounted on the surface of the circuit board.
What is Through-Hole Technology (THT)?
It is also called "thru-hole." It is the mounting scheme used for electronic components that involves the use of leads on the components that are inserted through holes drilled in printed circuit boards.
What is a ball grid array (BGA)?
A rectangular or square array of solder balls placed on one surface.
What is a Surface-Mount Device (SMD)?
An electronic device made for mounting or placing electronic components directly onto the surface of printed circuit boards (PCBs).
What is a Package on Package (PoP)?
Package on Package (PoP) is an integrated circuit packaging method that allows for higher component density in devices, such as mobile devices. It involves stacking two or more packages vertically via a standard interface to route signals between them.
What are the common questions regarding PCB Assembly?
Common inquiries often cover minimum order quantities, response times, and specific services related to manufacturing.
What are the types of PCB Assembly?
- Surface Mount Technology (SMT): Components are mounted directly onto the PCB, allowing for higher component density and automated assembly processes.
- Through-Hole Technology (THT): Components are inserted through drilled holes and soldered onto pads on the opposite side of the board, providing strong mechanical bonds suitable for high-reliability applications.
What is the PCBA process?
- Solder Paste Application: Applying solder paste to the PCB pads.
- Component Placement: Placing electronic components onto the PCB.
- Soldering: Securing components using reflow or wave soldering techniques.

- Lead Times: Evaluate their production and delivery timelines.
- Cost-Effectiveness: Compare pricing structures and value-added services.
- Communication Channels: Look for responsive and clear communication throughout the process.
What are the different types of PCBs?
- Single-Layer PCBs: Contain one layer of conductive material, suitable for simple electronics.
- Double-Layer PCBs: Have conductive layers on both sides, allowing for more complex circuits.
- Multilayer PCBs: Consist of three or more conductive layers, enabling high-density and complex designs.
CCA versus PCBA: What's the difference?
PCBA (Printed Circuit Board Assembly): Involves assembling individual components onto a printed circuit board (PCB) to create a functional unit.
CCA (Circuit Card Assembly): Comprises multiple PCBs assembled together to form a complete electronic circuit.
