A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components using the copper (conductive path) which happens to be made by etching copper clad. PCB can also be called as printed Wired Board (PWB). The PCB Depaneler without component is raw PCB & PCB with component is called printed circuit board assembly this means 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 will still be costly due to the high setup charges. Single Sided Board (SSB) The Printed Circuit Board which contains 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 contains over two copper layers. Material Used for Printed Circuit Board (PCB) Conductive Layer is essentially is of thin copper foil the base is of glass epoxy (insulating materials) some types are as below.
– The Past the first is using for prototype creation of printed circuit board. Prototype PCB means the limited nos. of PCB that is for R & D purpose of new product or modification of existing product. The cooper etching (Photo etching) method is widely is commonly used by large scale PCB manufacturing Companies across world.
– Screen printing method is cost saving, but it really compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is hard to achieve with this method. But nevertheless some companies are utilizing this to manufacture the reduced 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 techniques save considerable time. But this procedure will not be a good choice for mass production of Printed Circuit Boards. Photo etching Using the here we will appear the steps involved for Printed Circuit Board manufacturing with photo Etching methods.
Let’s start from beginning how the Printed Circuit Boards are created. Suppose We 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 store. First I have to send the gerber files to him for quotation in that I actually have to mention few reasons for having my requirement Including Die Tooling, 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 your data & allows the quotation. Following are Factors pcbflex play vital role deciding the buying price of 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.
After accepting quotation the PCB Router Machine goes for pre-engineering of gerber data. This is accomplished in Cam department of your company or many service beuro are available that provide cost effective service to Printed Circuit Boards Industry.
Why service beuro? Saves expense on OEM license cost Saves expense on Salary, bonus & other great things about Employee. Also the service beuro provide cost effective Solution on the other hand you must increase salary, bonus & other great things about employee on consistent basis. What Cam dept do after getting the consumer data? Cam dept. carefully studies the gerber data. If found any required missing file the consumer is informed immediately. When all information & info is received, the cam dept. starts the pre-engineering in the job.
