Adequate heat dissipation is essential for semiconductor devices. When a device exceeds a specified junction temperature, the device can be damaged, not perform correctly, or can have a reduced operating life. Semiconductor packages must dissipate heat from the chip to the external environment (i.e. to the PCB, air, etc) to keep the semiconductor device below a certain temperature threshold. For most devices, the most efficient way to dissipate the heat is through the package external I / O connections and into the PCB that it is mounted to. For Ball Grid Array (BGA) packages, the external I / Os are solder balls. Variable pitch packages pose advantages in heat dissipation without introducing significant costs.

A perforator is composed of a punch head for perforating on a material, a rotation driver for making said punch head to rotate, a reciprocating driver for making said punch heat to move axially, and a motor for driving said both drivers.

The invention discloses an organic electroluminescence display panel and a display device. A data writing unit is used to write a first preset voltage to the gate of a drive transistor, a detection unit is used to receive the drive current of the drive transistor, and the detection line is used to calculate the voltage. drive the current, and adjust the gate voltage of the drive transistor until the amount of change in the voltage on the detection line is a preset value, thereby calculating the change amount of the drive voltage of the light emitting device by calculating the change amount of the gate voltage of the drive transistor, and then The obtained corresponding aging condition of the light-emitting device.
