A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components using the copper (conductive path) which can be produced by etching copper clad. PCB is additionally known as printed Wired Board (PWB). The PCB Depaneler without component is raw PCB & PCB with component is known as printed circuit board assembly it implies the raw PCB is assembled with electronics components.
Nowadays PCB (raw) become highly affordable especially Single sided Board (SSB) & Double Sided Board (DSB). Multi layers PCB continue to be costly because of its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which has just one track (copper) layer is called SSB. Double Sided Board (DSB) The Printed Circuit Board which contains two track (copper) layer is known as DSB. Multi layer Board The Printed Circuit Board which has over two copper layers. Materials Used for Printed Circuit Board (PCB) Conductive Layer is basically is of thin copper foil the base is of glass epoxy (insulating materials) some types are as below.
– The Very Last the first is using for prototype manufacturing of printed circuit board. Prototype PCB means the limited nos. of PCB which can be for R & D purpose of new product or modification of existing product. The cooper etching (Photo etching) strategy is widely is commonly used by large PCB manufacturing Companies around world.
– Screen printing strategy is cost saving, nevertheless it compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is tough to achieve with this method. But still some companies are utilizing this to produce the low cost Printed Circuit Boards.
– PCB milling is adopted recently for quick turn Printed Circuit Boards manufacturing. The Printed Circuit Boards are milled on cnc machine mechanically with routers (end mill). These methods save great deal of time. But this procedure is not really helpful for mass creation of Printed Circuit Boards. Photo etching With all the below we can look the steps involved for Printed Circuit Board manufacturing with photo Etching methods.
Let’s start from beginning exactly how the Printed Circuit Boards are produced. Suppose I have requirement of Printed Circuit Board I am going to search the Printed Circuit manufacturer during my region with competitive rates. Select one from their website. First I have got to send out the gerber files to him for quotation because We have to mention few aspects of my requirement For example Flex PCB Punching, PCB finish copper, Masking, silk screen color (Automatically it can be masking PISM green, silk is white), HAL, Lead free, Delivery time. Once this data reach to Printed Circuit Board manufacturer he studies the data & gives the quotation. Following are Factors pcbflex play vital role deciding the price tag on Printed Circuit Board. Quantity, Minimum track, spacing & minimum drill diameter (Keep minimum track thickness & spacing between two connection 6 to 8 mill to minimize cost) Always verify the output (gerber data) before sending it to manufacturer.
After accepting quotation the PCB Router Machine is true of pre-engineering of gerber data. This is achieved in Cam department of your company or many service beuro can be found which provide economical company to Printed Circuit Boards Industry.
Why service beuro? Saves expense on OEM license cost Saves expense on Salary, bonus & other advantages of Employee. Also the service beuro provide cost effective Solution on the flip side you will need to increase salary, bonus & other advantages of employee on consistent basis. What Cam dept do once you have the customer data? Cam dept. carefully studies the gerber data. If found any required missing file the customer is informed immediately. When information & details are received, the cam dept. starts the pre-engineering of your job.
