HDI board
At present, the use of polyphenyl ether (PPO or PPE) resin is a good development direction, whether from high frequency materials or high speed materials.

PCB manufacturing enterprises lean production thinking
TPM and other high-end knowledge, but ignore the field management, ignore the most basic production activities of the people and equipment.
PCB is mainly divided into
The following is its structure diagram (about circuit symbols and functions will be explained later) :IC design: CMOS devices and their circuits，
Circuit board machining line spacing is small
The following are the main points and points for attention in selection of PTC self-restoring fuses of overcurrent devices arranged by Shuokai Electronics.
set of circuit board machining table
It is characterized by surface mounting of components and reflow welding technology. It has become a new generation of assembly technology for electronic products manufacturing.
The characteristics of PCB galvanizing are summarized as follows
Under normal circumstances, the electronic products we use are made of pcb plus a variety of capacitors, resistors and other electronic components designed according to the circuit diagram
Circuit board processing file for various purposes
As the temperature increases, the holding current and trigger current will decrease, so it is important to know the temperature of the environment in which PPTC is applied.
General structure of inverting logic gates
in dynamic power consumption, in addition to the capacitor power consumption when flipping, there is also the short-circuit power consumption caused by the simultaneous on-off of PMOS and NMOS when the gate * signal is flipping.
CMOS gate circuit
The following is its structure diagram (about circuit symbols and functions will be explained later) :IC design: CMOS devices and their circuits
PTC self - recovery fuse selection points
Another class of clamp type overvoltage devices are clamp type overvoltage devices with transient suppression diode, varistor, patch varistor and ESD discharge diode.
Operating frequency drops
mainly to check the open circuit and short circuit inspection of the line, as well as the use of visual inspection board quality. Packaging and shipment: the qualified board will be packaged and finally shipped to the customer.
Circuit board processing we provide material loss
The rectifier tube QL for bridge rectifier uses a 15-20A silicon bridge, which is compact and has a fixing screw in the middle, which can be directly fixed on the aluminum plate of the housing for favorable heat dissipation.
