A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components using the copper (conductive path) which is made by etching copper clad. PCB is also known as HDI display pcb distributor. 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 particularly 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.

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