We understand short and accurate lead time is essential in today’s rapidly changing market place. Customers need to know the exact date of the PCBs delivery so they can prepare the project schedule ahead of time. With Circuit engineering Co.,Ltd, lead time is considered as Printed Circuit Board Manufacture time + shipping time, no extra waiting time! Our standard lead-time starts from 5 to 9 working days, and 4 to 5 weeks for large volume production orders.
Multilayer Printed Circuit Board Manufacturing main production difficulties compared with the characteristics of conventional circuit boards, high-level electronic multilayer circuit boards have the characteristics of thicker boards, more layers, denser lines and vias, larger unit size, and thinner dielectric layers. Impedance design control and reliability requirements are more stringent. 1.1 Difficulties in inter-layer alignment Due…
Electronic Multilayer PCB Boards are generally defined as high-level multi-layer circuit boards with 10 layers to 20 layers or more, which are more difficult to process than traditional multi-layer circuit boards, and have high quality and reliability requirements. They are mainly used in communication equipment, high-end servers, and medical electronics, aviation, industrial control, military and…
Crack ARM STM32F070RC Microcontroller Flash Memory and extract STM32F070RC flash memory source code; sometimes there are automatic industry device with PCB which applied STM32F070RC microcontroller, in order to clone the PCB board with schematic diagram, the embedded firmware needs to be readout from its flash memory; The external interrupt/event controller consists of 23 edge-detector lines…
Printed Circuit Board Raw Material plays an important role for its electricity performance stability and reliability for electronic device and appliance, which is also has great impact on the process of reverse engineering PCB board; The most used PCB board is FR4, which uses glass fiber cloth as a reinforcing material and epoxy resin as…
PC Board Composition Components contains two important ITEMs: Core and PP (Prepreg, semi-solid sheet). Both surfaces of the Core are covered with copper foil, which is used as a conductive layer, and the two surface layers are filled with solid material, which is composed of reinforcing material glass fiber impregnated with solid resin. There is…
Optoelectronic Interconnection Circuit Board Reliability Analysis mainly refers to strong vibration and shock which are quite common in the equipment on automobiles, ships and aircrafts during their startup and operation. This service environment can be described as broadband random vibration. When serving in a random vibration environment, the Optoelectronic Interconnection Circuit Board Reliability Analysis will…
Printed Circuit Board Copper Plating is another important method for PCB board surface treatment: In this process, all surface areas and drill holes are plated with copper, and some resist is poured on the unneeded copper surface, and then an etching resist metal is plated. Even for a medium-sized printed circuit board, this requires an…
Growing a metal build-up layer on the circuit board tracks and through holes can electroplate the circuit, which is described as PCB Board Circuitry Pattern Electroplating: In this process, only the places where the circuit patterns and through holes are designed accept the generation of the copper layer and the metal plating of the etching…
The precise technology required by electronic products and the strict requirements of environmental and safety adaptability have promoted considerable progress in PCB Circuit Board Electroplating Practice and specify the printed circuit board electroplating necessity. This is clearly reflected in the technology of manufacturing high-complexity and high-resolution multilayer circuit boards. In electroplating, through the development of…
The interconnection of various modules in electronic equipment often requires the use of a printed circuit board socket with spring contacts and a printed circuit board with connecting contacts designed to match it. These contacts should have a high degree of wear resistance and very low contact resistance to illustrate the Necessity of Printed Circuit…
