FAQ

Silver and aluminum wire how to identify? There are several options?

Find a small amount of sulfur, wipe on silk, a smear is not black, silver, aluminum wire. If blackened, the fire will turn silver again. The advantage is that it hardly hurts the material.

Why are the microwave tubes of the microwave oven prone to be bad and how to repair them?

Copper is supposed to conduct electricity more efficiently than aluminum, so the pipes are easily broken by large currents

How to judge the quality of aluminium wiredrawing oil / aluminium alloy drawing oil?Industry experts hope to help answer

Base oil is the raw material of aluminum wire drawing oil important. His quality of drawing oil quality is crucial, she decided the high temperature performance, drawing oil shear performance, viscosity temperature characteristics, antioxidant capacity, performance and evaporation loss will cause sludge and carbon smoke, harmful ingredients idle base oil production according to standard. Can be divided into standard oil and non standard oil. Standard oil (base oil production in accordance with the relevant standards) generally refers to the previous Sinopec Corporation issued neutral paraffine standard, intermediate and naphthenic base oil standards (SN, ZN, DN). The so-called "non standard" refers to the 3 basis Oil Corporation and Sinopec issued relatively, generally lower than the standard oil company. Non standard base oil containing sludge, originally yellow metal impurities, to some extent, this will lead to the poor performance of aluminum wire drawing oil, anti settling The oxidation is poor. So we often see that the non-standard aluminum wire drawing oil production oil color is brown, brown, black and brown. The standard base oil production drawing oil is golden yellow, yellow, pale yellow (such as AMTT S580A al Mary oil) or light transparent (such as an S590 aluminum small oil) oil. The color is very beautiful, peanut oil, cooking oil. We like

Pure copper wire for 1 points and 2.5 copper clad wire which is better?

Copper is good, I guess the 1 of your family is to change the electricity, the rest of the bar, in order to clean up, use 3*1.0 (RVV)

Detailed flow of LED packaging?

Beijiao. The expansion will extend good crystal ring crystal has good scraping gum machine on the silver paste layer on the surface of the back of silver paste. Silver paste. Suitable for bulk LED chips. Apply the right amount of silver paste onto the PCB printed circuit board with a dispenser.

What are the processes for LED production?

Pressure welding: the electrode is connected to the LED core by aluminum wire or wire bonder, which is used as the lead for the current injection. LED installed directly on the PCB, the general use of aluminum wire welding machine. (making white TOP-LED requires wire welding machine)

Is the wire on the diode a type of P and N semiconductor? Or P semiconductor?

Not semiconductors, but metalsLook, this is not a PN junction. It should be a Schottky diode, a diode made of metal and a semiconductor, and a Schottky barrier

Can solder aluminum wire with tin wire?

Had better not, according to the chemical terms, if welded, all metal, and the water vapor in the air to form a galvanic cell, it will accelerate corrosion
