铜线球焊点焊接

Copper solder ball welding

    金价格日益高涨,用金量大的封装厂大喊吃不消,从首季财报中的毛利率侵蚀1~3个百分点可以看出,这也让寻求下一代替代材料的动作更加急迫。封装厂和设备商等双管齐下,近期加快脚步开发采用铜线(Copper Wire)取代金线的方式,期以降低材料成本压力。

    铜 线除了单价较金线为低之外,其导电性佳,尤其在高电流之下,业者往往用需要打数条金线,铜线具有导电性佳的优点,因此只需要接1条铜线,就能达到金线的导电水平,具有降低成本的作用。惟其缺点在于铜容易氧化、保存困难,这也是让铜线无法快速取代金线的主因。
     在空气中铜线容易氧化,所以铜线必须存放于包装盒中以减少环境带来的氧化,然而,一旦打开包装放于焊线机上,铜线被暴露于空气中而因此氧化,放置于设备上铜线的使用寿命,大概是3到4天,虽然研究表明长时间暴露仍然可用于焊接,但是由于在空气球在形成的时候受到严重氧化而需要一个惰性气体的环境,所以需要在设备上加一套铜线专用装置,这套装置利用惰性气体氮气保护暴露在空气中的铜线,然而加入5%后氢气的混合气体更常用,因为氢原子可以和氧原子反应,可以去除铜线的氧化,为了在混合气体环绕保护下形成铜球,所以在打火杆上设计了一套保护装置,使得在里面的铜线可以在混合气体的保护下形成铜球.

Copper solder ball welding

    Rising gold prices, gold large packaging factory shouting too much, erosion of 1 to 3 percentage points from the first quarter earnings can be seen in the gross margin, which also seek to make the next generation of alternative materials more urgent action. Packaging plant and equipment providers and other two-pronged approach to accelerate the pace of the recent development of the use of copper (Copper Wire) gold substituted ways of reducing the material cost pressures.

    In addition to copper than the unit price of gold was lower than the electric conductivity good, especially under high current, the industry often need to fight with several gold, copper has the advantages of good electrical conductivity, and therefore only need to take a copper wire You can achieve the level of conductive gold thread, with lower cost of action. But their disadvantage is that copper is easily oxidized, save trouble, which is so rapidly replacing copper wire gold wire can not be the main reason.
     Copper is easily oxidized in air, so the copper must be stored in the box to reduce the oxidation of the environment, however, upon opening the package put on the wire bonders, copper is exposed to air oxidation and thus placed in the device on the life of copper, about 3-4 days, though studies have shown that prolonged exposure can still be used for welding, but because when the ball in the air formed by oxidation of the need for a serious inert gas environment, it is necessary on the device plus a copper dedicated device, this means the use of an inert gas such as nitrogen to protect the copper exposed to the air, but after adding 5% hydrogen mixed gas is more commonly used as a hydrogen atom and an oxygen atom can be the reaction can be removed copper oxidation, in order to surround the mixed gas is formed under the protection of copper balls, so the ignition rod designed a protective device so that the copper inside copper balls can be formed under a protective gas mixture.

working principle;
       This device is hydrogen by adjusting the valve, add nitrogen to obtain a stable hydrogen and nitrogen gas mixture having a certain percentage. On-demand adjustment.

  The main equipment components and functions;
Control valve; the control mechanism of the system, which is directly affected by the operation of the actuator control. It is hydrogen, a key component ratio of nitrogen mix.
2 hydrogen partial meter; a detection means of the system (small flowmeter is hydrogen INSTRUMENT traffic controllers), show the percentage of the ratio of hydrogen gas content, and the percentage content of hydrogen is converted into a current signal 4-20.
3 smart display regulator; is the system controller, the hydrogen partial Instrument current signal with the set value comparison calculation, the calculation result is converted into a current signal 4-20mA actuator needed. Intelligent display regulator has mixed gas concentration alarm output.
4 electrical converters; the implementation of the present system, it is the role of the switch controller to send control signals to the pressure signal, push the control body movements.
Electrical converter gas source, is a key component to ensure electrical converter to accept the controller, the control signal into a pneumatic signal; 5 filter regulator.
6 mixing tank; the hydrogen, nitrogen mixing ratio.
7 ratio meter; the flow rate ratio of the mixed gas is displayed.
8 pressure controller, for nitrogen, hydrogen pressure alarm output.

Process;
After the original hydrogen shut-off valve, regulator valve, regulating valve regulates added nitrogen, the ratio of gas mixture through the mixing tank, mixing ratio of the gas mixture through a small flowmeter control the hydrogen partial cytometric analysis shows the percentage content of hydrogen, hydrogen iNSTRUMENT the percentage content of the hydrogen is converted into 4-20mA current signal, the intelligent display regulator hydrogen partial instrument current signal is compared with the set value calculation, calculation results are converted into 4-20mA current signal drives electrical converters, converted pressure signals, and adjusting the stroke of the valve spool is proportional to the pressure signal, so as to regulate the gas mixing ratio function stable mixture adjusted to the required flow rate. use to work through the outlet valve.
