Turnkey PCB Assembly: Streamlining Your Electronics Manufacturing from Concept to Completion

What is Turnkey PCB Assembly ? A Comprehensive Definition

Turnkey PCB Assembly is a service that provides a comprehensive, end-to-end solution where a single provider, like Mustar, handles all stages of Printed Circuit Board production. This includes:

• Design Review: Assessing files for their manufacturability.
• Component Sourcing: Purchasing all electronic components.
• PCB fabrication: manufacturing the bare circuit board.
• Assembly: Mounting components through holes and surface-mount.
• Quality Check: Perform comprehensive quality checks
• Final testing & packaging: Ensuring complete functionality and secure packing.

Turnkey implies that the product will be delivered “ready to use immediately,” eliminating the need for the customer to manage multiple suppliers or complex supply chain logistics. This service is available as ” complete turnkey ” (where everything is handled by the provider) or ” partially turnkey ” (where some components are supplied by the client).

Turnkey PCB assembly process: From design to delivery

The following steps are essential to a typical turnkey PCB Assembly process:

1. Design Review: A provider (e.g., Mustar) reviews the design files of the client (Gerbers, BOMs, Pick-and-Place) in order to determine their manufacturability and efficiency. This allows them to identify potential issues as early as possible.
2. Component Sourcing: By leveraging strong supplier networks, this provider procures electronic components that are authentic, high-quality, and at competitive prices. Mustar has a system that includes a 500K IC data query online and consists of an experienced purchasing staff to ensure reliable and efficient component supply.
3. PCB Fabrication: Bare PCBs are produced according to specifications, adhering to industry standards such as IPC-6012. Mustar is capable of producing PCBs with up to 64 layers, including FR-4, ROGERS, and high-frequency boards.
4. PCB assembly (SMT and THT): The components are placed on the PCBs and soldered using automated pick-and-place machines, reflow, and wave soldering. Mustar uses advanced assembly technology to handle miniature components such as 01005s, BGAs, and QFNs.
5. Quality Inspection & Testing: Rigorous tests include Automated Optical Inspection for visual defects, Automated X Ray Inspection for BGAs, In-Circuit Testing for electrical connectivity, and Functional Testing to simulate real-world performance. Mustar provides free programming and functional tests, adhering strictly to IPC A-610E standards. They perform E-test, an X-ray test, AOI testing, QC, and 100% functional tests.
6. Packaging and Shipping Final: PCBAs that have been completed and tested are packaged securely and shipped directly to the customer.
