A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components utilizing the copper (conductive path) which is created by etching copper clad. PCB is additionally known as printed Wired Board (PWB). The PCB Separator without component is raw PCB & PCB with component is called printed circuit board assembly it indicates 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 merely 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 contains a lot more than two copper layers. Material 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 Final the initial one is using for prototype creation of printed circuit board. Prototype PCB means the limited nos. of PCB which is for R & D intent behind cool product or modification of existing product. The cooper etching (Photo etching) way is widely is commonly used by large 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 very hard to achieve with this method. But nonetheless some companies are employing this to produce 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 methods save considerable amount of time. But this procedure is just not ideal for mass manufacture of Printed Circuit Boards. Photo etching Together with the here we will 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 manufactured. Suppose We have requirement of Printed Circuit Board I am going to search the Printed Circuit manufacturer inside my region with competitive rates. Select one from them. First We have to send out the gerber files to him for quotation for the reason that I have to bring up few reasons for having my requirement Including PCB Punching, PCB finish copper, Masking, silk screen color (By default 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 info & 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 reduce 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 accomplished in Cam department in the company or many service beuro are available that provide economical company to Printed Circuit Boards Industry.
Why service beuro? Saves expense on OEM license cost Saves expense on Salary, bonus & other benefits of Employee. Also the service beuro provide affordable Solution on the other hand you have to increase salary, bonus & other great things about employee on consistent basis. What Cam dept do after getting the client data? Cam dept. carefully studies the gerber data. If found any required missing file the consumer is informed immediately. When all information & data is received, the cam dept. starts the pre-engineering from the job.
