A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components utilizing the copper (conductive path) which can be created by etching copper clad. PCB is likewise known as printed Wired Board (PWB). The PCB Depaneler 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 very inexpensive especially Single sided Board (SSB) & Double Sided Board (DSB). Multi layers PCB continue to be costly due to its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which has merely one track (copper) layer is named SSB. Double Sided Board (DSB) The Printed Circuit Board which includes two track (copper) layer is named DSB. Multi layer Board The Printed Circuit Board that has over two copper layers. Materials Used for Printed Circuit Board (PCB) Conductive Layer is actually 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 manufacture of printed circuit board. Prototype PCB means the limited nos. of PCB which is for R & D intent behind new product or modification of existing product. The cooper etching (Photo etching) way is widely is commonly used by large scale PCB manufacturing Companies throughout world.
– Screen printing method is cost saving, nevertheless it compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is hard to achieve using this type of method. But still some companies are employing this to produce 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 methods save considerable amount of time. But this technique will not be ideal for mass manufacture of Printed Circuit Boards. Photo etching Using the below we will appear the steps involved for Printed Circuit Board manufacturing with photo Etching methods.
Let’s start from beginning exactly how the Printed Circuit Boards are produced. Suppose I actually have requirement of Printed Circuit Board I will search the Printed Circuit manufacturer within my region with competitive rates. Select one from them. First I actually have to deliver the gerber files to him for quotation in that I have got to say few things about my requirement Such as PCB Punching, PCB finish copper, Masking, silk screen color (Automatically it really is masking PISM green, silk is white), HAL, Lead free, Delivery time. If 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 lessen 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 done in Cam department in the company or many service beuro can be found which offer cost-effective service to Printed Circuit Boards Industry.
Why service beuro? Saves expense on OEM license cost Saves expense on Salary, bonus & other advantages of Employee. Also the service beuro provide affordable Solution on the flip side you will need 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 information & info is received, the cam dept. starts the pre-engineering of your job.
