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.
On the printed circuit board, copper is used to interconnect the components on the substrate. Although it is a good conductor material for forming the pattern of the conductive path of the printed circuit board, it will also be exposed to the air for a long time. It is easy to lose luster due to…
How to choose PCB Board Raw Laminate Material is a quite common subject from the very begining of printed circuit board design, to printed circuit board manufacturing, Choosing a PCB material must strike a balance between meeting design requirements and mass production and cost. The design requirements include electrical and institutional components which can learn…
Manufacturing Circuit Board According to Reverse Engineering PCB Gerber File is a reverse order of PCB design to production, Through reverse engineering printed circuit board, The physical electronic circuit board is converted into the electronic file of the required circuit board diagram which include Gerber file, CAD file, layout scheme and BOM list, then the…
In addition to the conductive layer and the dielectric layer, the laminated structure of the PCB further includes a solder resist layer and a silk screen layer which are PCB Board Layer Composition. The solder mask covers the surface signal layer (top layer and bottom layer) of the PCB and is mainly composed of a…
Electronic PCB Circuit Board Conductive Layer can be set either as a signal layer for wiring or as a planar layer for power or ground. In the process of desigining a PCB, the signal layers are called “positive films” and the planar layers are called “negative films”, which differ in design methods. The positive film…
Since the 1990s, more and more chips have been packaged in BGA (ball array) packages, and as technology continues to evolve, the Pitch (the center distance between solder balls and solder balls) of the package has become smaller and smaller. In this case, the solder balls located in the inner layer of the chip are…
Since the invention of the PCB by the Austrian engineer Paul Eisler in 1936 and its use in radio circuits, the PCB has been widely accepted and rapidly developed by the electronics industry. Originally, PCB Circuit Board Structure was single-sided, and later developed to double-sided, then four layers, and now it has grown to multiple…
PCB is an abbreviation of Printed Circuit Board, which is also commonly referred to as electronic circuit board and PCB Card. According to the definition of modern electronics, it is processed into a board with certain size based on an insulating laminated sheet with epoxy plus resin, fiberglass, and at least one conductive pattern and…
Hereby we would like to take an example of a 4 layer circuit board will be described to explain how the arrangement and combination of various Standard Multilayer Circuit Board Stackup Structure are preferred. For the commonly used 4-layer boards, there are several stacking methods (from top to bottom). (1) Siganl_1 (Top), GND (Inner_1), POWER…
PCB prototyping means that after the PCB reverse engineering, engineer will conducts small quantity trial production order to the PCB manufacturer. As a matter of fact, There is no specific requirement for the quantity of PCB prototype production. Design engineer should place order to produce PCB prototypes before mass production to verify if PCB schematic…
