A boss who runs a lighting factory in Guzhen Haizhou, due to the unsatisfactory turnover of operating funds and the pressure to pay off debts, decided to flee back to Sichuan to avoid debts. With the assistance of the Sichuan police, the ancient town police successfully captured the absent boss Tang.
On February 25 this year, the supplier Mr. He reported that the owner of the lighting factory that had been in business had suspected to abscond. According to Mr. He, since it began to supply LED lighting materials and other materials to the lighting factory in March last year, the payment of the payment by the two parties has become the default. The date of payment and payment is not related to the lighting factory. People Tang. Subsequently, Mr. He learned from other suppliers that the lighting factory had been closed down and chose to call the police. There are also nine suppliers who have encountered the same problems as Mr. He. According to preliminary statistics, the lighting factory operated by Tang has arrears of more than 1.1 million yuan.
The police quickly conducted a visit investigation and information research and judgment on the lighting factory, initially locking the criminal suspect Tang to have a major suspected crime. The suspect Tangmou is very likely to flee back to his hometown in Sichuan, so the police sent a chasing team to Nanchong City, Sichuan Province to conduct investigation and evidence collection and pre-emptive work.
On April 2, with the assistance of the Sichuan police, the suspect Tang was arrested. On April 10, Tang was taken back to Zhongshan Guzhen for further trial.
According to the suspect Tang, confessed that because of his poor management, he was unable to repay his debts, and Meng Meng gave birth to the idea of ​​abandoning the factory to escape. During the period, he went to Chongqing to collect debts, but he was unable to repay the suppliers' money, so he decided to sneak back to his home to hide debts. The suspect Tang confessed to the criminal facts of the suspected contract fraud. At present, the criminal suspect Tang has been criminally detained by the Guzhen police in light of alleged contract fraud. The case is under further investigation.
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.
