Frequently Asked
Questions

Soldering defects are imperfections in solder joints that can lead to failures in electrical circuits. They include cold solder joints, solder bridges, insufficient or excessive solder, tombstoning, and voids.

EMS (Electronics Manufacturing Services) companies procure electronic components through strategic partnerships with suppliers, bulk purchasing to reduce costs, and utilizing supply chain management tools to forecast demand and ensure timely component delivery.

OEM stands for Original Equipment Manufacturer, a company that designs and manufactures a product. CEM (Contract Electronics Manufacturer) is similar to EMS, providing manufacturing services to OEMs under contract. The term CEM is often used interchangeably with EMS, though EMS may offer a broader range of services, including design and after-sales support.

Turnkey PCB manufacturing and assembly is an all-inclusive service covering the entire process of creating printed circuit boards, from fabricating the PCBs to sourcing components and completing the assembly, offering a ready-to-use board to the customer.

Passive Components: Resistors, capacitors. Active Components: Transistors, diodes. Integrated Circuits: Microprocessors, memory chips.

BGA reballing is the process of removing old solder balls from a BGA component and replacing them with new ones. This repair technique is used to fix defective BGA solder joints or to reattach a BGA component to a PCB.

High frequency PCBs are designed to operate at frequencies typically above 1 GHz. They require specific materials and design considerations to minimize signal loss and maintain performance in applications like telecommunications and advanced computing.

Many PCB manufacturers specialize in low volume production, catering to custom projects, prototypes, and small-scale production needs. These providers offer flexibility and quick turnaround times.

Stencil material can be metal (such as stainless steel) for durability and precision in applications like PCB assembly, or plastic and other polymers for various arts and crafts or industrial applications.

PCB soldering is the process of joining electronic components to a printed circuit board (PCB) using solder, a fusible metal alloy, to establish a strong electrical connection between the component leads and the board's conductive pathways.
