A Printed Circuit Board or PCB is Mechanical Assistance & electrically wired the electronic components using the copper (conductive path) which happens to be made by etching copper clad. PCB is also called as printed Wired Board (PWB). The PCB without component is raw PCB & PCB with component is called printed circuit board assembly it means the 6 layer telegraph pcb is assembled with electronics components.Nowadays PCB (raw) become pretty inexpensive especially Single sided Board (SSB) & Double Sided Board (DSB). Multi layers PCB are still costly due to 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 has two track (copper) layer is called DSB.

Multilayer layer mobile phone PCB The Printed Circuit Board which has more than two copper layers. Material Used for Printed Circuit Board (PCB) Conductive Layer is basically is regarding thin copper foil the base is related with glass epoxy (insulating materials) Common Ways associated with producing printed circuit board:Copper etching (Photo etching) ,Screen printing ,PCB MillingFrom above the very first two are widely used for mass manufacturing associated with printed circuit board.- The Last one is using for prototype generation for printed circuit board. Prototype PCB means the limited nos. related with Multilayer layer telegraph pcb which happens to be for R & D objective of new product or modification connected with existing product. The cooper etching (Photo etching) method is broadly is used by large scale PCB production Companies around world. - Screen printing method is cost saving, but it compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is fairly hard to achieve with this method. But still some enterprises are using this to manufacture 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 ways save lot of time. But this method is not useful for mass manufacturing relating to Printed Circuit Boards. Photo etching With the below we will look the steps involved for 8 layer mobile phone PCB manufacturing with photo Etching ways.Let's begin with beginning how the Printed Circuit Boards are manufactured. Suppose I have requirement related with Printed Circuit Board I will search the Printed Circuit maker in my region with competitive rates. Select one from them. First I have to send the gerber files to him for quotation in that I have to mention few things about my requirement Such as PCB thickness, PCB finish copper, Masking, silk screen color (By default it truly is masking PISM green, silk is white), HAL, Lead free, Delivery time. When this data reach to Printed Circuit Board producer he studies the data & gives the quotation. Following are Factors which play vital role deciding the price regarding Printed Circuit Board. Quantity, Minimum track, spacing & minimum drill diameter (Keep minimum track thickness & spacing between two connection 6 to 8 mill to reduce cost) Always verify the output (gerber data) before sending it to maker.
