Цель изобретения - повышение надежности отвода зарядов с плат полупроводниковых приборов.The purpose of the invention is to increase the reliability of charge removal from the boards of semiconductor devices.

На чертеже показана конструктивная схема устройства.The drawing shows a structural diagram of the device.

’ Устройство состоит из монтажной платы 1 с техническим рисунком 2, алюминиевой фольги 3 и микросхемы 4 с контактными штырями 5 (механизм для соединения штырей с кромкой не показан). Οτι верстия в монтажной плате 1 соответствуют расположенйю штырей микросхема 4. Фольга 3 заземлена.’The device consists of a mounting plate 1 with a technical drawing 2, aluminum foil 3 and a microcircuit 4 with contact pins 5 (a mechanism for connecting the pins to the edge is not shown). The holes in the circuit board 1 correspond to the pin position of the microcircuit 4. The foil 3 is grounded.

Устройство работает следующим образом.The device operates as follows.

На монтажной плате 1 устанавливается свежая (не использовавшаяся ранее) фольга и заземляется. Затем с помощью механизма для соединения штырей с фольгой осуществляется прокалывание фольги штырями в местах, 5 где расположены отверстия в монтажной плате, и микросхема устанавливается на ней для хранения или осуществления каких-либо технологических операций.On the circuit board 1, fresh (not previously used) foil is installed and grounded. Then, using the mechanism for connecting the pins to the foil, the foil is pierced with pins in places 5 where the holes in the circuit board are located, and the microcircuit is installed on it for storing or performing any technological operations.

В процессе прокалывания штыри очи.щаются от загрязнений, и при толщине фольги 0,01-0,05 мм надежно соединяются с кромкой. Поскольку фольга |заземлена, обеспечивается и надежное заземление штырей, а следовательно, и надежный отвод зарядов с микросхем. После выполнения технологических операций (например, пайки) фольга удаляется вытягиванием с полным ее разрывом.In the process of piercing, the pins are cleaned from contamination, and with a foil thickness of 0.01-0.05 mm, they reliably connect to the edge. Since the foil | is grounded, a reliable grounding of the pins is provided, and, consequently, a reliable removal of charges with microcircuits. After performing technological operations (for example, soldering), the foil is removed by pulling with a complete gap.

Claims

The invention relates to a technique for combating the harmful effects of static electricity and can be used in the development of devices for the removal of electrostatic charges by means of grounding connections for electronic applications. The purpose of the invention is to increase the reliability of charge removal from semiconductor device boards. The drawing shows the structural diagram of the device. The device consists of a mounting plate 1 with technical drawing 2, aluminum foil 3 and a microcircuit 4 with contact-; pins 5 (the mechanism for connecting the pins to the edge is not shown). 0t holes in the circuit board 1 correspond to the location of the pins on the chip 1 4. Foil 3 is grounded. The device works as follows. On the circuit board 1, installing; 1, svezhivaetsya fresh (not used before) 4 silts and grounded. Then, using the mechanism for connecting the pins with the foil, the foil is penetrated by pins at the places where the holes are located in the circuit board, and the chip is mounted on it for storing or carrying out any technological operations. I In the process of drilling, the pins are cleaned of dirt, and when the foil thickness is 0.01-0.05 mm, they are securely connected to the edge. Since the foil is grounded, a reliable earthing of the pin and, consequently, a reliable discharge of charges from the microcircuit is ensured. After performing technological operations (e.g. soldering), the foil is removed by pulling with its full rupture. Apparatus of the Invention A device for removing static electricity charges from objects equipped with pin contacts, comprising a contact electrode connected to a grounding circuit, made in the form of a strip of conductive material, and a mechanism for connecting the pins and strip by puncturing the last pins, characterized by that, in order to improve the reliability of charge removal from semiconductor device microcircuits, the gasket is made of metal foil.
