Yesterday's lawyer informed that Amazon cut a single Changhong television case and the court ruled that our consumers won the case. The court ordered Amazon China to ship Changhong TV for $161 in 10 days. "Yesterday, Shanghai consumer Mr. Ning excitedly told consumer electronics spending network," Grandma has hope to see the beloved Changhong TV. â€
On November 26 last year, Amazon China launched Thanksgiving Promotion. Among them, Changhong's 32-inch LCD TV is priced at 161.99 yuan in a one-off spike. Ultra-low prices have caused many consumers to place orders and snap up orders. But one day later, consumers have received emails from Amazon China that are out of stock and cancel orders. Consumers found that Changhong TV continued to sell on Amazon China for 1489 yuan. Only by the then Amazon's own sales into Changhong store sales.
Consumers who feel discriminated against have established the QQ Rights Protection Group of “Amazon Changhong Litigation Groupâ€. Among them, 169 consumers entrusted lawyers to submit a lawyer's letter to Amazon China, requesting Amazon to deliver goods on time and apologize. However, Amazon China has not responded yet.
On December 24 last year, China's first legal service search site, Crafts.com, stated that it would provide free lawyer services to the rights-protected consumers and bear all litigation costs. In January of this year, Mr. Ning and three other consumer representatives submitted an indictment to Beijing Chaoyang Court requesting Amazon China to fulfill orders for delivery of televisions. On March 3, the Chaoyang Court in Beijing officially opened its court to hear a case of a single TV cut by the Amazon.
Mr. Ning said that the lawyers told him yesterday that Chaoyang Court had issued a verdict on April 15. He saw the verdict read: "According to the provisions of Articles 39, 40, and 107 of the "PRC Contract Law," it was decided that Amazon China will sell him within 10 days of the verdict. Changhong 32-inch TV with a price of 161 yuan. And give him evidence preservation fee of 1,000 yuan and attorney fees of 4,000 yuan. Overdue will double the interest paid on debt.
Via In Pad PCB
What is Via In Pad? In shortly,via in pad is the via holes are at the SMD pad.The vias are very small,usually under 0.3mm.Why and how? First is there is no enough space to layout,you have to put the vias and holes closer even together.Second it helps thermal management and for high frequency boards,it may help improve signals.
Because the SMD pads are for SMD components loading,so the solder can not flow to inner layer or the other side when assemble.That is the most important for via in pad board.
How PCB manufacturers like us to do via in pad board? We will fill all vias with non-conductive epoxy and plate copper over it ,so the vias are flat same as others. Many PCB factories are unable to do such capability.
The key technology is how we fill vias and guarantee there is no any solder (surface finishing) in the holes.
Filled via in pad is a way to achieve intermediate density with an intermediate cost compared to using blind/buried vias. Some of the key advantages associated with using the via in pad technology are:
.Fan out fine pitch (less than .75mm) BGAs
.Meets closely packed placement requirements
.Better thermal management
.Overcomes high speed design issues and constraints i.e. low inductance
.No via plugging is required at component locations
.Provides a flat, coplanar surface for component attachment
Via in big pads are not a big problem.but for BGA,that is technology.As BGA pads are very small,10mil or 12mil,and there is no enough space.Manufacturing is not easy as other boards.
