Assembléia PCB

Quais são as almofadas redondas na parte inferior de uma PCB?

These test pads and the test points are probably used in different parts of the manufacturing process. Por exemplo,

  • The test points may be used for board-level testing and the test pads may be used for system-level testing. These are test pads designed for use with a pogo-pin test fixture, also known as a bed-of-nails test fixture. These fixtures have a specially shaped array of pogo-pins that press down and make contact with the test pads on the board under test.
  • Ou, perhaps, the test pads are used for programming and/or debugging firmware, when the device under test is clamped into the bed-of-nails fixture.
