A Printed Circuit Board or PCB is Mechanical Assist & electrically wired the electronic components using the copper (conductive path) which can 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 raw PCB is assembled with electronics components.Nowadays PCB (raw) become extremely inexpensive especially Single sided Board (SSB) & Double Sided Board (DSB). 8 layer mobile phone PCB are still costly due to its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which has one track (copper) layer is called SSB. Double Sided Board (DSB) The Printed Circuit Board which has two track (copper) layer is called DSB.

Multi layer Board The Printed Circuit Board which has more than two copper layers. Material Used for Printed Circuit Board (PCB) Conductive Layer is basically is for thin copper foil the base is about glass epoxy (insulating materials) Common Approaches related with creating printed circuit board:Copper etching (Photo etching) ,Screen printing ,Multilayer layer telegraph pcb.From above the very first two are vastly used for mass production connected with printed circuit board.- The Last one is using for prototype production relating to printed circuit board. Prototype PCB means the limited nos. connected with PCB which happens to be for R & D motive for new product or modification concerning existing product. The cooper etching (Photo etching) method is widely is used by large scale PCB production Enterprises across 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 extremely 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 PCB supplier. The Printed Circuit Boards are milled on cnc machine mechanically with routers (end mill). These methods save lot of time. But this method is not useful for mass generation relating to Printed Circuit Boards. Photo etching With the below we will look the steps involved for Printed Circuit Board manufacturing with photo Etching approaches.Let's begin with beginning how the Printed Circuit Boards are manufactured. Suppose I have requirement about Printed Circuit Board I will search the Printed Circuit supplier 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 is masking PISM green, silk is white), HAL, Lead free, Delivery time. When this data reach to layer telegraph pcb manufacturer he studies the data & gives the quotation. Following are Factors which play vital role deciding the price connected with 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 manufacturer.
