Title:
POGO PIN COOLING SYSTEM AND COOLING METHOD, AND ELECTRONIC COMPONENT TESTING DEVICE HAVING POGO PIN COOLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/087085
Kind Code:
A1
Abstract:
A pogo pin cooling system and cooling method, and an electronic component testing device having the system, comprising a coolant circulation module (2). The coolant circulation module (2) comprises a coolant supply channel (21) and a coolant recovery channel (22) respectively communicated with slot inlets (Sin) and slot outlets (Sout) of a wafer slot (S). When the wafer slot (S) accommodates an electronic component (C), the coolant circulation module (2) supplies a coolant (Lc) into the wafer slot (S) by means of the coolant supply channel (21) and the slot inlets (Sin), and the coolant (Lc) flows through a pogo pin (Sp) and then flows back to the coolant recovery channel (22) through the slot outlets (Sout). The circularly-flowing coolant (Lc) can not only cool the pogo pin (Sp) in the wafer slot (S), but also cool the bottom surface of the electronic component (C) and a solder ball contact (Cb), to avoid a solder ball from contaminating the pogo pin (Sp) and the wafer slot (S) due to high-temperature softening or even melting.
