Repair method of CPU pin break

repair method of CPU pin break

CPU is a very delicate computer accessories, may be due to transport and maintenance of improper and broken pins, although its internal circuit intact, but because of the inability to use and was sentenced to "death penalty." Through the practice test, the following two methods are summarized, which can be used to repair the CPU with broken pin.

Prepare 20W electric iron in advance, sharpen the tips to facilitate welding, and note that the soldering iron should be well grounded, if there is no grounding, only after pulling out the plug to use heat welding, otherwise the CPU is the risk of inductive charge breakdown.

　　Method One: Pin Welding method

(1) The CPU cut off the surface of the foot, with solder and rosin on its rapid tin, solder evenly attached to the broken foot can be.

(2) The CPU broken foot (if lost, can be replaced by pins and electronic components of the pin) scraping, in the same way tin.

(3) with double-sided glue to the CPU fixed on the desktop, the left hand tweezers with a broken foot, so that the end of the tin with the CPU broken feet, the right hand with electric iron quickly welded together. Some rosin can be used to make the solder joints small and smooth.

(4) The CPU is carefully inserted into the CPU socket, if inserted, can be used to weld the blade carefully trimmed, inserted after the boot, all normal, finished!

　　Method Two: Direct connection method

(1) Take 30 cm long diameter of about 0.2 mm of enameled wire, with the same method as above to weld the end of the CPU at the broken foot, requiring a flat and small welding point.

(2) The CPU is inserted into the CPU seat, so that the enameled wire from the gap between the two leads.

(3) Careful observation of the motherboard CPU seat on the back, found that there are many rows into a column of small solder joints, arranged with the CPU of the pin relative should be found with broken feet corresponding to the solder point, the other end of the enameled wire can be carefully welded up. Note that enameled wire should be as short as possible in order to reduce external interference.

(4) Check the welding is correct, installed, turn on the power, screen display CPU is detected, repair success!

Have used the above two methods on a broken three feet of the pentium/166cpu on the use of the same time to achieve success, the use of all normal six months.
