A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components making use of the copper (conductive path) which happens to be produced by etching copper clad. PCB is likewise called as printed Wired Board (PWB). The PCB Depaneler without component is raw PCB & PCB with component is named printed circuit board assembly it 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 remain costly because of its high setup charges. Single Sided Board (SSB) The Printed Circuit Board that has only one track (copper) layer is known as SSB. Double Sided Board (DSB) The Printed Circuit Board that has two track (copper) layer is called DSB. Multi layer Board The Printed Circuit Board which has a lot more than two copper layers. Materials 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 manufacture of printed circuit board. Prototype PCB means the limited nos. of PCB which can be for R & D reason for new product or modification of existing product. The cooper etching (Photo etching) technique is widely can be used by large PCB manufacturing Companies all over world.
– Screen printing way 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 particular method. But nonetheless some companies are employing this to manufacture 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 techniques save considerable time. But this procedure is not helpful for mass production of Printed Circuit Boards. Photo etching Using the here we will look the steps involved for Printed Circuit Board manufacturing with photo Etching methods.
Let’s start from beginning just how the Printed Circuit Boards are manufactured. Suppose I have got requirement of Printed Circuit Board I am going to search the Printed Circuit manufacturer inside my region with competitive rates. Select one from their store. First I have to deliver the gerber files to him for quotation in this I actually have to bring up few reasons for having my requirement For example Flex PCB Punching, PCB finish copper, Masking, silk screen color (Automatically it is actually masking PISM green, silk is white), HAL, Lead free, Delivery time. If this data reach to Printed Circuit Board manufacturer he studies the info & provides the quotation. Following are Factors pcbflex play vital role deciding the 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 applies to pre-engineering of gerber data. This is achieved in Cam department of the company or many service beuro can be purchased that provide cost effective company to Printed Circuit Boards Industry.
Why service beuro? Saves expense on OEM license cost Saves expense on Salary, bonus & other advantages of Employee. Even the service beuro provide cost-effective Solution alternatively you have to increase salary, bonus & other benefits of employee on regular basis. What Cam dept do once you have the individual data? Cam dept. carefully studies the gerber data. If found any required missing file the client is informed immediately. When all information & data is received, the cam dept. starts the pre-engineering in the job.
