Printed Circuit Board Duplicating
Printed Circuit Board Duplicating can re-manufacture obselete electronic PCB card according to its restore schematic diagram and Gerber file, the cloned PCB card will provide the exactly same functions as original circuit board which has out of market for decades;
Printed Circuit Board Duplicating is a industry which requires sufficient experience, Circuit engineering co.,ltd has been in this industry for years and have accumulated lots of experiences. We have seen Printed circuit boards from over several hundreds of different products in various industries, such as air conditioning, Liquid Crystal Diode TV, digital photograph frame, and other automatic industry products, etc.
In view of a printed circuit board design engineers, some of these Printed circuit boards have good design features, some others not. The only standard for design a good Printed circuit board is whether it can be checked and viewed by engineers from manufacturing factory clearly and effortlessly, without any misunderstanding which can cause the wrong operation and production.
Design the drill hole on the printed circuit board is critical to this process, and most important and most directly problem is the design about minimum drill hole diameter, and generally speaking, the minimum hole diameter is from the through hole on the Printed circuit board which can reflect on the cost directly, some of the Printed circuit boards can actually use 0.5mm drill hole but being placed 0.3mm. which can cause the increasing cost of production.
And consequently, if the Printed circuit board production cost rise up, they will increase their quote too; besides, if there are too many drill holes, such as PCB board applied on DVD machine, and digital camera frame, and according to our experience there are around 500-600 drill holes on it is sufficient, instead has been designed over 1000 drill holes
Anyway, people is tend to believe that more through holes can bring benefit to the thermal dissipation. There should be a balance for this point, engineers should not only take the thermal dissipation into consideration, but also the Printed circuit board production budget, take an example, one of our clients used to work on a web camera product, and after duplicating Printed circuit board, which has great demanding quantity on the printed circuit board manufacturing, but its Printed circuit board has too much drill hole which has greatly affected its total cost accompany with its increasing demanding quantity, so after discussion with their engineers, the hole diameter has been enlarged correspondingly, and delete the through hole on the copper area, and the four heat dissipation holes on the main microcontrollers have been replaced by several 0.3mm drill hole through which bring down the drill hole cost, and those slots hole which has very strict dimension tolerance and very difficult to control the tolerance, we suggest the customer to change it from 1.0mm X 1.2mm to 1.2mm round hole directly.
