On November 23, the “General Technical Conditions for LED Fluorescent Lamps for Indoor Lighting†was held in Jinan. Experts from Shandong Academy of Sciences, Shandong Provincial Quality Inspection Institute, Jinan University, Liaocheng University and other relevant units attended the meeting. The participating experts reviewed the standards one by one and agreed to pass them.
The general technical conditions for LED fluorescent lamps for indoor lighting were drafted by Shandong Shuyuan Lighting Technology Co., Ltd. This standard mainly specifies the product classification, requirements, test methods, inspection rules, etc. of LED fluorescent lamps for indoor lighting. It aims to standardize the technical requirements of LED fluorescent lamps for indoor lighting in this province, provide basis for product design and inspection, and promote LED application products. Implementation and promotion.

Cheap 12 Layers PCB stackup and thickness
We are one of the few manufacturers in China that can manufacture 12-layer PCB boards on a large scale.
The 12-layer board can usually be manufactured smoothly on a 1.6mm thick FR-4 board. But we've seen more 14- to 16-layer boards are being fabricated into 1.6mm thick boards, but the number of manufacturers that can produce them is limited to manufacturers that can produce HDI boards. Those who can produce HDI boards are increasing.
12 Layers PCB– Heavy industry boards or boards with may tracks
For industrial PC design, 12-layer circuit boards are more popular. Compared with other multi-layer circuit boards, such as four-layer circuit boards, 8-layer circuit boards, 10-layer circuit boards, The price of the 12-layer PCB is still reasonable.

12 layer stackup – 4 GNDs
I use this stackup a lot, provides GND shielding of high speed signals and has tightly coupled Power-Ground planes:
Signal / Solid GND plane / High speed signals and important buses / Solid GND plane / Power / Power or Mixed with signals / Power or Mixed with signals / Power / Solid GND plane / High speed signals and important buses / Solid GND plane / Signal
12 layer stackup – two additional signal layers
Signal / Solid GND plane / Signal / Signal / Solid Power Plane / Power or Mixed with signals / Power or Mixed with signals / Solid Power Plane / Signal / Signal / Solid GND plane / Signal
