LED lighting must lead others to break the technical bottleneck

The prospect of LED domestic market is optimistic, which has led to the acceleration of mergers and acquisitions of downstream industrial chains by LED companies at home and abroad, attracting many investors to enter this industry. The climax of investment industry has reappeared. At the same t

Suggestions on improving the energy saving problem of LED lighting

The biggest selling point of LED lighting is energy saving, but often the market is limited by the cost of the product, materials, and heat dissipation technology, so that the demand for energy saving has a discount because of the light efficiency factor. Energy conservation is currently mainly

The difference between triode and mos tube in circuit design

What is the difference in the working nature of the triode and MOS tube when we do the circuit design:

1. Transistor current control, MOS tube is voltage control.

2, the cost of the problem: the triode is cheap, MOS tube is expensive.

3,

Laser direct molding to achieve low cost 3D integrated circuits

Laser Direct Molding (LDS) technology uses laser ablation and metallization to create electronic circuitry on injection molded plastic parts while providing mounting surfaces for surface mount components, ultimately enabling 3D-mid.

Laser direct structuring cre
