Probe apparatus
View Patent ↗A probe apparatus and a probe system are provided. The probe apparatus uses a larger printed circuit board to dispose a plurality of testers. The layout of each of the testers on the circuit board is modified accordingly, such that more number of the testers can be disposed on the circuit board and the pin count of the probe apparatus is increased. In addition, the probe apparatus can be installed in the test tool. Accordingly, the testing efficiency of the present test tool can be substantially promoted and the cost of the overall testing can be effectively reduced.
1. A probe apparatus suitable for testing a semiconductor device, comprising:
a circuit board comprising a first surface and a second surface, each having a center respectively;
a plurality of pogo pads disposed on the first surface in at least one ring arrangement with a center coinciding with the center of the first surface;
a plurality of probe pins disposed on the second surface of the circuit board and electrically coupled to the pogo pads accordingly;
a plurality of capacitors disposed outside the ring arrangement of the pogo pads on the first surface of the circuit board in a ring arrangement, wherein a center of the ring of the capacitors coincides to the center of the first surface, and a distance from the center to any capacitor is larger than a distance from the center to any pogo pad; and
a plurality of relays disposed outside the pogo pads on the first surface of the circuit board in a ring arrangement and electrically coupled to the pogo pads and the capacitors, respectively, wherein a center of the ring of relays coincides with the center of the first surface, and a distance from the center to any relay is larger than a distance form the center to any pogo pad.
2. The probe apparatus of claim 1 , further comprising:
a ceramic head disposed on the second surface of the circuit board for disposing the probe pins.
3. The probe apparatus of claim 1 , wherein the relays are disposed outside the ring arrangement of the capacitors on the first surface of the circuit board, wherein a center of the ring of the relays coincides with the center of the first surface.
4. The probe apparatus of claim 1 , wherein the capacitors are disposed outside the ring arrangement of the relays on the first surface of the circuit board, wherein a center of the ring of the capacitors coincides with the center of the first surface.
5. The probe apparatus of claim 1 , wherein the shape of the circuit board comprises a circular shape.
6. The probe apparatus of claim 1 , wherein the pogo pads are arranged in a multiple-concentric-ring arrangement.
7. The probe apparatus of claim 1 , wherein the probe pins are arranged in a square array.
