Frequently Asked
Questions

Environmental stress refers to extreme conditions a product might encounter during its lifecycle, including temperature variations, humidity, vibration, and shock. These conditions can reveal hidden weaknesses in the product's design or manufacturing.

MDA testing is limited to detecting physical and basic electrical defects. It cannot assess component functionality, circuit performance under power, or complex issues like timing errors.

If a PCB fails functional testing: The failure is analyzed to determine the cause (component, assembly process, design issue). The PCB may undergo rework or repair to correct the identified issue. After repairs, the PCB is retested to ensure it now passes functional testing, verifying its readiness for final assembly.

Functional testing is conducted by applying specific inputs to the PCB and measuring the outputs to compare against expected results. Test equipment may include signal generators, power supplies, and measurement devices, configured according to the PCB's operational specifications.

Small volume PCB refers to the production of PCBs in limited quantities, typically for prototyping, custom projects, or initial market releases. This approach allows for detailed attention to quality, design iteration, and testing.

Low volume manufacturing involves producing small quantities of products, typically ranging from a few units to several thousand. It's ideal for prototypes, market testing, and custom or niche products.

Simplify design for manufacturability. Choose common, cost-effective components. Conduct extensive testing to reduce revisions.

Basic knowledge of SMT includes understanding the types of SMT components, the equipment used in the SMT line, the assembly process, and the techniques for ensuring high-quality soldering and component placement.

Consignment assembly is a manufacturing service where the customer provides all or most of the components required for the PCB assembly to the service provider. The assembler then uses these supplied parts to complete the assembly process.

Turnkey assembly is a manufacturing service where the provider oversees the entire assembly process of a product, from sourcing materials and components to the final assembly, ensuring the product is ready for use or sale immediately upon delivery.
