베드 오브 네일 픽스처란?
베드 오브 네일 픽스처는 PCB 산업에서 회로 기판의 성능을 검증하는 데 사용되는 전통적인 전자 테스트 픽스처로, 특히 인-서킷 테스트 공정에서 사용됩니다. 이 픽스처는 회로 기판의 각 테스트 지점에 연결된 못 침대와 유사한 여러 개의 딱딱한 테스트 픽스처로 구성됩니다. 스프링이 장착된 이 픽스처는 압력을 가하여 테스트 포인트와 적절히 접촉하도록 합니다. 이러한 픽스처의 배열은 매트릭스와 같은 패턴을 형성하여 보드의 여러 테스트 지점을 동시에 테스트할 수 있습니다.
Controlled by test software, programming is performed on the test points and test signals, allowing testers to gather information about all the test points. The selection and assembly of the fixtures are determined based on the distribution and positions of the test nodes or points on the board. The primary purpose of a bed of nails fixture is to detect and resolve defects and design errors associated with manufacturing PCBs.

In order to verify the presence of the correct signal at each test point, the circuit board must be powered on and the measurements of the various test points must be taken.
What Is a Fixture in PCB
Generally speaking, a test fixture or test jig is the component that contains the bed of nails used for testing the PCB or assembled product. Some PCB test fixtures can also be utilized for functional testing of edge connectors. These fixtures can be operated either mechanically or pneumatically.
What Is an ICT Fixture
An ICT fixture is used to test individual components of a printed circuit board one by one. It compares the test results with a software model of the component’s parameters, which is known as “schematic verification” because of the testing method used.
Why Use a Bed of Nails
