Description
Technical field
The present invention is a kind of new microbonding point device for testing creep resistance, belongs to Material Joining Technology field, suitable
Test for microbonding point croop property, be applied to the reliability of mechanics, calorifics and electricity that microelectronics connects
Research.This apparatus structure is simple, it is possible to realizes multiple sample and tests simultaneously.
Background technology
Microelectronics is connected in electronic product play dual parts to be mechanically connected and electrical connection, therefore microbonding
The integrity problem of point obtains extensive concern.Croop property is to weigh the important indicator of the lasting service ability of solder joint,
Therefore the croop property test of microbonding point is one of the most commonly used method for evaluating reliability.
Complete the croop property test of microbonding point and need to meet following requirement: (1) the most controlled additional should
Power；(2) creep life of on-line monitoring solder joint；(3) ambient temperature；(4) repeatable.For microbonding
The croop property test of point there is also following particularity: the size of (1) microbonding point is little, generally micron order,
Therefore test applied stress is also the least, can meet requirement within general 50N；(2) microbonding point is compacted
Become deflection in test less, fracture failure i.e. can occur in general tens micrometer ranges, therefore use tradition
The method of strain-gauge test dependent variable can not reach corresponding precision.(3) microbonding point is statistics knot creep life
Really, it is required for multiple sample to test.
It is universal tensile testing machine or creep testing machine that widely used method is tested in creep at present, and it is the most former
Reason is to use servomotor as power source, and leading screw, screw are as execution unit, it is achieved testing machine moves horizontal stroke
The speed controlling of beam.Test if carried out high-temerature creep, also need to be equipped with high temperature furnace and temperature control system.
Legacy equipment structure is complicated, expensive.The shortcoming of its maximum is to be simultaneous for multiple style simultaneously
Carrying out synchronism detection, general set of system can only be for a style.Creep test period is long, generally number
Ten days even several months long, therefore traditional method can not meet the requirement of existing microbonding point croop property test.
