Technical field

The present invention relates to microwave components maintenance technique fields more particularly to a kind of for microwave components soldering electric connector Repair method and device.

Background technique

It is brazed that the poor air-tightness of the appearance during electric connector, the saturating rate of pricker is low for ground connection, electric connector for microwave components The problems such as fracture, common repair method are thermal station+blowing hot wind.The method is flexible, and universality is strong, but heat-affected zone is big, returns Repair that efficiency slow (single-piece is greater than 20min), to be also easy to produce fifth wheel, gold-plated component success rate low (less than 20%).Chang Yikuan etc. is in " electricity Sub- product level Hermetic Package reprocesses new method " in using Loctile290 anaerobic adhesive leak stopping, leak rate are carried out to the electric connector of soldering Reach 10-8mbar.l/s, meets the requirement of GJB548B-2005.The method is easy to operate, at low cost, the period is short, but anaerobic adhesive Easy to moisture absorption, long-term work is easy to aging, can only play the role of temporary leak stopping, is unable to satisfy military electronic product high reliability and wants It asks.

Summary of the invention

The technical problems to be solved by the present invention are: proposing a kind of new side reprocessed for wave component soldering electric connector Method, the speed for reprocessing microwave components is fast, does not bring fifth wheel, to realize permanent leak stopping.

A kind of repair method for microwave components soldering electric connector provided by the invention, including metal assembly and metal Electric connector to be repaired on component, further comprises the steps of:

(1) induction coil is selected according to the shape size of electric connector to be repaired, to reduce thermal losses, improves heating effect Rate;

(2) it connect induction coil with induction power supply, and sets the power of induction power supply;

(3) electric connector to be repaired is placed near induction coil, closure switch make induction coil nearby generate alternation Magnetic field is to heat the solder around electric connector to be repaired;

(4) after solder melts, switch is disconnected, electric connector to be repaired is further repaired.

The method that the above microwave components soldering electric connector is reprocessed is easy to operate, the period is short;Can also local heating to avoid Other electronic device overagings;Without dismantling to component, the repair time 20min of single electric connector drops to 5min;It will not Generate fifth wheel;The success rate of reprocessing of gold-plated component reaches 90%.

It further, further include that weldering is helped to the junction coating of metal assembly and electric connector to be repaired before heating Agent accelerates solder to melt, keeps wetting abundant.

Further, further include scaling powder around electric connector after cleaning maintenance, and to the metal group after maintenance Part carries out air tightness test, and whether the electric connector after examining maintenance is qualified.

Further, further include being cooled down while heating to induction coil, avoid induction coil because of temperature mistake It is high and melt, extend the service life of induction coil.

Further, the switch is power supply control pedal, and the power supply control pedal normal condition is to disconnect, and is pressed When for closure, when disconnection, is truncated power supply, and when closure powers on;By the on-off of power supply control pedal control induction power supply, make to tie up The process repaired is more convenient, avoids the problem that operation not in time.

It further, further include the metal assembly being placed in baking oven to keep the temperature before heating, the temperature of the baking oven It is set as 120 DEG C, when heat preservation is 10 minutes a length of, to guarantee that metal assembly is heated evenly.

Further, the diameter of induction coil is 1- bigger than the diameter of the electric connector to be repaired in the step (1) 2mm keeps the region of heating controllable;

The output power of induction power supply is set as 65%-70% in the step (2);

The electric connector to be repaired is placed in the induction coil side when heating in the step (3), and with the sense Coil is answered to keep the soldering distance of 1.5mm-1mm, closure switch heat 5-8s;

(11) stop heating after solder melts, using ceramic pincette to the electric connector applied force to be repaired, to prevent Only it is emerged, and the electric connector and connecter hole after guaranteeing maintenance have good ground connection pricker permeability.

Further, the diameter of induction coil is 3- bigger than the diameter of the electric connector to be repaired in the step (1) 4mm, guarantee operation when it is unobscured with it is easy to operate;

The output power of induction power supply is set as 75%-80% in the step (2);

Electric connector to be repaired is placed in immediately below the induction coil when heating in the step (3), and with the induction Coil disconnects switch after keeping the soldering distance of 0.5mm-1mm, closure switch to preheat 3-4s, then recloses switch heating 5- 7s makes circuit jump circle because induction coil, which works long hours, makes the excessively high easy fusing of temperature, therefore first preheats to heat afterwards and can avoid The case where jumping circle occurs;

(21) using ceramic pincette that electric connector to be repaired is fast from the connecter hole of metal assembly after solder melts Speed is extracted, and simultaneously switches off switch, new electric connector is placed in the electric connector hole;

(22) and step (3)-(21) are repeated until solder remaining in hole removes substantially;To be repaired be electrically connected is extracted to remove Solder remaining in electric connector hole after device is connect, to connect new electric connector later.

(23) successively preforming solder ring, scaling powder, new electric connector are placed in the electric connector hole;

(24) output power of power supply is set as 65%~70%, and closure switch heat 5~8s, use after the thawing of solder ring Ceramic pincette is to new electric connector applied force, to prevent it from emerging.

The present invention also provides a kind of device for repairing for microwave components soldering electric connector, including induction power supply, senses Coil, the electric connector to be repaired on metal assembly and the metal assembly are answered, the induction power supply is connect with the induction coil, The induction coil heats the electric connector to be repaired by generating alternating magnetic field, to melt surrounding solder;Further include The power supply control pedal that is connect with the induction power supply and for the cooling chilled water system for answering coil to connect, the chilled water system with The vacant port connection of the two of induction coil provides cold water when induction coil work to cool down induction coil.

Further, to keep induction coil more durable, the induction coil be multi-stage reducing copper pipe, the number of turns according to The induced electromotive force size selection needed, at least 1 circle and formation closing structure, the number of turns of the bigger needs of the induced electromotive force needed More, the induction coil surface is high temperature resistant, insulation, wear-resisting material.

By using above technical solution, the beneficial effects of the present invention are: solving microwave components electric connector reprocesses effect Rate is low, success rate is low, the halfway problem of leak stopping.
