A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components using the copper (conductive path) which is created by etching copper clad. PCB is also known as printed Wired Board (PWB). The PCB Depaneler 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 very inexpensive especially Single sided Board (SSB) & Double Sided Board (DSB). Multi layers PCB will still be costly due to its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which includes only one track (copper) layer is referred to as 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 which includes more than two copper layers. Materials 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 Very Last one is using for prototype creation of printed circuit board. Prototype PCB means the limited nos. of PCB which happens to be for R & D intent behind cool product or modification of existing product. The cooper etching (Photo etching) strategy is widely is utilized by large scale PCB manufacturing Companies throughout world.
– Screen printing way is cost saving, but it compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is tough to achieve using this type of method. Yet still 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 techniques save considerable time. But this technique is not helpful for mass manufacture of Printed Circuit Boards. Photo etching With all the below we can look the steps involved for Printed Circuit Board manufacturing with photo Etching methods.
Let’s start from beginning the way the Printed Circuit Boards are manufactured. Suppose I have requirement of Printed Circuit Board I am going to search the Printed Circuit manufacturer during my region with competitive rates. Select one from them. First I have to send out the gerber files to him for quotation in that I have got to mention few aspects of my requirement Such as PCB Punching, PCB finish copper, Masking, silk screen color (Automatically it is masking PISM green, silk is white), HAL, Lead free, Delivery time. When this data reach to Printed Circuit Board manufacturer he studies the data & 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 minimize 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 achieved in Cam department in the company or many service beuro can be purchased which offer affordable company to Printed Circuit Boards Industry.
Why service beuro? Saves expense on OEM license cost Saves expense on Salary, bonus & other benefits associated with Employee. Also the service beuro provide cost-effective Solution on the other hand you must 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 information & information is received, the cam dept. starts the pre-engineering in the job.
