Description

TECHNICAL FIELD

[0001] The utility model belongs to tool fixture technical field relates to a circuit ultrasonic scanning platform. BACKGROUND

[0002] For plastic package integrated circuit package test, ultrasonic scanning detection is an indispensable inspection item. Whether in the plastic package integrated circuit packaging process, or integrated circuit appraisal, ultrasonic scanning detection technology will be used to detect the existence of plastic package integrated circuit internal plastic package cavity, plastic package foreign matter, chip delamination and frame delamination and other abnormalities. For frame delamination anomaly, because the front and back of the frame are wrapped by the plastic package, the front and back of the circuit need to be detected by ultrasonic scanning respectively to ensure the accuracy of the detection result.

[0003] For the strip-shaped product during integrated circuit packaging, the product size is the same, and the product is extremely convenient to take and adjust the direction, and the ultrasonic scanning detection efficiency is higher. But for the integrated circuit cut into single, it is necessary to take and adjust the direction for each circuit respectively, and at present, it is adjusted manually, which seriously reduces the ultrasonic scanning detection efficiency.

[0004] At present, the ultrasonic scanning detection method for single circuit mainly has two kinds. One method is to paste the circuit on the carrier plate with adhesive tape. This method can arrange the circuit during the ultrasonic scanning detection time, replace the carrier plate after the ultrasonic scanning detection of the last board is completed, and perform the ultrasonic scanning detection of the next board. This method can shorten the ultrasonic scanning detection period, but cannot perform transmission scanning, cannot ensure the accuracy of the product ultrasonic scanning detection, and the adhesive tape will remain on the circuit, affecting the appearance of the product and subsequent board welding. Another method is to use a general plastic tray instead of adhesive tape and carrier plate. This method can shorten the ultrasonic scanning detection period, but also cannot perform transmission scanning, and when the product direction is changed, the circuit and the plastic tray need to be moved out of the water surface, and when the circuit is immersed in the water surface again, many bubbles will be generated, affecting the judgment of the ultrasonic scanning detection.
