FR4 circuit board, how to distinguish Between Ordinary PCB And High Frequency PCB?
The high-frequency printed circuit board is pressed with a whole piece of epoxy glass cloth, and the color of the high frequency circuit board is relatively uniform and bright; at the fracture, you can easily see the white powder with the color of rice by scraping it with your hand or other tools. White. The density is higher than that of ordinary FR4 pcb, and the weight is heavier.
Ordinary FR4 PCB is made of glass fiber board (composite board). The color of the back substrate is different. Large stripes can be seen on the back of the entire board. Check for different types of PCBs.
What Failure Phenomenon Will Occur When The Performance Of The High-Frequency Printed Circuit Board Is Poor
The poor performance of the high-frequency printed circuit board is mainly due to the low dielectric constant value which affects the working stability of the high-frequency circuit. It may cause signal attenuation, frequency offset drift, and severely stop vibration. The overall electrical performance index is reduced.

Multilayer PCB China Benefits
Multilayer PCB China have high assembly density and smaller size.
During multilayer PCB manufacturing, Multilayer circuit board laying is convenient and the laying length is shortened
The wiring between the electronic components of the multi-layer printed circuit board is reduced, and the data signal transmission rate is improved during PCB manufacturing service, such as multilayer PCB prototype and multilayer PCB fabrication.
For electronic products with higher heat dissipation requirements, a metal core heat dissipation layer can be set on the multilayer circuit board to facilitate the requirements for special functions such as shielding and heat dissipation

Production process of metallized half-hole PCB
For the front inversion, to prevent the quality of the product and the need to make corrections in the later process, the production process of this type of board is processed according to the following process: a drilling (drilling, gong groove-plate surface plating-external Optical imaging-pattern plating-co-drying-half-hole processing-film stripping, etching, tin stripping-other processes-shape
Main points of metallized half-hole PCB production
The specific metallized PCB half hole are processed in the following way: all metallized half-hole PCB holes must be drilled in the pattern after plating, and one hole at the intersection of the two ends of the half-hole should be drilled before etching.
The engineering department formulates the MI process according to the process
The metal half-hole is the second-drilled half-hole drilled during the first drilling (or gong), after the image is plated, and before the etching. It is necessary to consider whether the copper will be exposed when the gong groove is shaped, and move the drilled half-hole into the unit.
he right hole is drilled first, and then the board is turned over (or mirrored) and the left hole is drilled to reduce the pulling of the copper of the inner hole of the half hole by the drill, resulting in the lack of copper of the hole.
The size of the drill nozzle for drilling the half hole depends on the spacing of the contour lines.
Draw the solder mask film, use the gong space as a stop point and open the window to increase 4mil treatment.
The designer's suggestion when designing the circuit
Change the distance from the edge line to the hole center. The general design is to place the hole center on the edge line and move the control center down. For example, the diameter of the hole is 1.4mm, the distance between the two holes is 2.54mm, and the board edge The distance between the line is 0.33mm from the center of the through hole, and the thickness of the plate is 0.6mm. The angle between the tangent to the cut point of the wall and the track of the milling cutter was 90 degrees before, but this time it is about 60 degrees. Because the board edge line is at a certain distance from the center of the through hole, the cutting angle of the milling cutter is changed, and the board thickness is extremely small, so the copper in the hole is not easily pulled out. The simultaneous improvement of small batch pcb design and production can greatly improve the production yield of PCB half-hole boards.
