Q:How do you weld it with ordinary electric welding?

There is a knack for correctly loading aluminum wire (also applicable to steel wire), which is very important for loading aluminum welding wires and avoiding welding failures. Hold the wire shaft safely with one hand to make sure it won't let loose. Once you open the cellophane wrapper, hold the loose end of the wire with the other hand before you put it into the drive wheel. Inexperienced people usually fail to grip the loose end and cause the entire bundle of wires to start loosening. If this happens, it will not be remedied and welding operations will be greatly affected - you will have to buy another bundle of wire.

Q:Where is the PN junction of point contact diode?

After adding the voltage, the fine aluminum wire melts at the contact point and penetrates into the melted part. In this way, the contact point is actually a p type semiconductor and attaches to the N type semiconductor to form a PN junction.

Q:What is the iron chromium aluminum wire

Usage: used in industrial electric stove, household appliance, far infrared equipment, etc..

Q:Is there an electric wire in the integrated circuit?

What is the integrated circuit, he is a semiconductor chip, you said that is not assembly PCB motherboard, motherboard integrated circuit, you see a amount of discipline is the integrated circuit chip, and CPU chip is the large super large scale integrated circuit.

Q:Is the LED Packaging Engineer demanding?

LED expansionAs the LED chip is still closely spaced after dicing, the spacing is very small (about 0.1mm), which is not conducive to the operation of the subsequent process. We use the expansion machine to expand the film on the bonding chip, and the LED chip spacing is stretched to about 0.6mm. Manual expansion can also be used, but it is easy to cause chip waste, waste and other undesirable problems.

Q:What's the side effect of washing aluminum wire basin with detergent?!

Magnesium and oxygen reaction at room temperature: see magnesium was black, polished with sandpaper is silver white. Do magnesium combustion experiments, to note that the crucible clamp, below the mat of asbestos net. Magnesium is ignited, combustion, produce a dazzling light, the formation of white smoke, put a lot of heat; 2Mg+O2 light - 2MgO.

Q:Is the polyurethane plastic made of transparent wrapped aluminum silk easy to yellow?

If you want permanent resistance to yellowing, you can only use the aliphatic, but the price of this raw material is high.

Q:Can I use the wire for the car radio or the aluminum wire?

You'd better not use iron wire

Q:What's the color of the copper core section of the cable?

Copper wire is not so pure, it should be yellow, after cutting, light problems should be pale, quite normal. Pure copper is red, but pure copper is softer and expensive.

Q:How to process aluminum wire into 0.1 mm aluminum wire, and the efficiency can not be too low

For FLMY1, FLMY2, FLMY3, FLMY4, granularity 0.16~0. (6063 aluminum alloy scrap), aluminum wire, aluminum profile scrap, mechanical processing aluminum scrap... Not only product quality is good, and processing cost is low, investment is little, quick effect.
