What is Burn-In Printed Circuit Board (PCB)?
A burn-in PCB is a printed circuit board that has undergone a burn-in Process. Burn-in boards are specially used as part of the ASIC reliability testing process during which components are stressed with heat to detect failures. These boards are generally made from materials that are capable of withstanding extreme conditions, like FR4 for moderate temperatures (125 °C) or Polyimide for higher temperatures (250 °C).
Burn-in assemblies are fitted with sockets and slots so that components can be placed and removed easily. During testing, the burn-in PCB with the components will be placed in a burn-in oven at an elevated temperature. This helps disclose hidden flaws in materials, design, and manufacturing that are likely to cause failure in their applications. The use of a burn-in board can assess and guarantee the durability of the components before deployment.
Advantages of Burn-In PCB:
- Reusable Design: Burn-in PCBs are fitted with sockets and slots, enabling easy placement and removal of components. This reusable design reduces costs and simplifies the testing process by allowing multiple components to be tested using the same PCB.
- Material Versatility for Extreme Conditions: Burn-in PCBs are made from high-performance materials like FR4 and Polyimide, which can withstand extreme temperatures up to 250°C. This versatility makes them suitable for testing components designed for high-stress environments.
- Enhanced Quality Control: By identifying defects during the burn-in process, manufacturers ensure a higher level of quality control, leading to more reliable products and fewer customer complaints.
PCB Directory has listed the leading Burn-In PCB fabricators and manufacturers and made them searchable through their location and capabilities. You can choose a country to filter and find local PCB manufacturers or companies nearby that can develop your Burn-In printed circuit boards. Additionally, you can filter Burn-In PCB suppliers based on specific capabilities such as the number of layers, material, and more. PCB Directory will then optimize the results to display manufacturers that meet your requirements.
