To deal with the problem that Electrostatic Separation of waste circuit board is high in purity, whereas relatively low in output/capacity,we developed multi-cylinder electrostatic separator and waste circuit winnower which is developed on the principle that the specific gravities of copper powder/grain and plastics are remarkable different..

另外针静电分离对废旧电路覆铜板的分离纯度高而产量比较小，我公司开发的多滚筒静电分离机和根据粉碎后的电路板中铜粉与环氧树脂粉的密度比重差距比较大的原理研制的废旧电路板气流分选机解决了分离产量问题。

The coreless PCB transformer concept has not received much attention,probably because there are misunderstandings: that planar winding with a few turns printed on a PCB is almost like a 'short-circuit' and that magnetic core is an essential component in transformer construction.

无铁心印制电路板变压器的概念没有受到人们很多关注，多半是因为存在误解：（i平面绕组在印制电路板上只能印制几匝，差不多像是&短路线&；在变压器结构中，磁心是根本的元件。

Its efficiency is testified by an application. The fixtureless tester can perform 100% test for PCB's connectivity through the probe movement. It takes a long time to test a PCB with low efficiency.

传统的飞针式在线测试仪必须通过大量的机械运动才能实现印刷电路板连接故障的完全测试，因此完成一块印刷电路板的测试需要较长的时间，检测效率较低。

The soft circuit board has an inner-cling body, a flectional body and an external body; the line layer of the soft circuit board has even numbers of contact fingers located on the external body; the inner-cling body clings to the glass substrate; width and rigidity of the flectional body are both smaller than those of the external body, thus the sensing region of the image-sensing wafer can be relatively moveable to the contact fingers.

该软性电路板具有一内贴部、一可弯曲部以及一外接部，该软性电路板的线路层具有复数个位于该外接部的接触指，该内贴部是贴附于该玻璃基板，并且该可弯曲部的宽度与刚性是均小于该外接部的宽度与刚性，以使该影像感测晶片的该感测区相对可动于该些接触指。
