Freescale Kinetis series is a microcontroller based on ARM CORTEX-M4 introduced by Freescale. Design of Freescale K60 Clock System As shown in the above figure, the Freescale K60 clock system can find that there are four source clock sources of the device: ① Internal reference clock sources, including Fast IRC and Slow IRC (IRC-Internal Reference […]

Base station, information communication between base stations. V2 is the key technology to realize intelligent transportation technology in the future. NXP, formerly known as Philips Semiconductor Company with a long history, has a very mature practical application scheme and technical platform for vehicle-to-outside information exchange (V2X). On the vehicle V2X communication, NXP provides complete solutions […]

Basic requirements of wiring in high-speed PCB design (1) the outlet of rectangular pad of 1)QFP, SOP, etc. package should be led out from the PIN center (generally, shape is used). (2) The distance from the wiring to the board edge is not less than 20MIL. ) (3) Other network vias and surface wiring are […]

Besides the selection of components and circuit design, good printed circuit board (PCB) design is also a very important factor in electromagnetic compatibility. The key of PCB design is to minimize the reflow area and make the reflow path flow in the designed direction. The most common return current problems come from cracks in the […]

With the continuous development and progress of electronic product technology, electronic products are gradually developing towards light, thin, small, personalized, highly reliable and multi-functional. Aluminum substrates and copper substrates are born in compliance with this trend. So, what is the difference between aluminum substrate and copper substrate? Generally, the aluminum substrate is single layer, which […]

One of the main purposes of circuit schematic design is to provide a network list for the design of pcb, and to prepare for the design of PCB. The design process of multi-layer pcb is basically the same as that of ordinary PCB, but the difference is that the wiring of the intermediate signal layer […]

Although many customers and friends have been deeply involved in the electronic industry for many years, as the saying goes: there are specialties in the technical field! Perhaps you are not sure about the real quality of PCB. Xiaobian has been working in the PCB industry for ten years. Today, I will simply talk to […]

Why is BOM so important in PCBA processing? In daily work, many customers who do PCBA processing will ask, do you have a BOM here? Why is BOM so important in PCBA processing? BOM means bill of materials. A BOM of a product, indicating how many spare parts are needed to assemble the product. All […]

Usually, customers need to ensure that product design can be seamlessly transferred from prototype manufacturing to mass production process. If there is a difference between the two, then the customer needs to bear the related costs and delays. Differences mean that extra costs need to be paid to eliminate them. In this process, new problems […]
