A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components while using copper (conductive path) which happens to be made by etching copper clad. PCB is also known as printed Wired Board (PWB). The PCB Separator without component is raw PCB & PCB with component is referred to as 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 only one track (copper) layer is named SSB. Double Sided Board (DSB) The Printed Circuit Board which includes two track (copper) layer is referred to as DSB. Multi layer Board The Printed Circuit Board which includes greater than two copper layers. Materials 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 Last one is using for prototype manufacture of printed circuit board. Prototype PCB means the limited nos. of PCB which can be for R & D function of new product or modification of existing product. The cooper etching (Photo etching) way is widely is used by large PCB manufacturing Companies across world.
– Screen printing method is cost saving, however it compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is tough to achieve with this method. But nonetheless 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 techniques save great deal of time. But this procedure is not really helpful for mass manufacturing 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 how the Printed Circuit Boards are made. 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 website. First We have to send out the gerber files to him for quotation in this I actually have to say few aspects of my requirement Such as Flex PCB Punching, PCB finish copper, Masking, silk screen color (By default it is actually 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 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 Depaneling Router is true of pre-engineering of gerber data. This can be done 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 associated with Employee. Even the service beuro provide cost-effective Solution however you have to increase salary, bonus & other advantages of employee on consistent basis. What Cam dept do once you have the client data? Cam dept. carefully studies the gerber data. If found any required missing file the client is informed immediately. When all information & info is received, the cam dept. starts the pre-engineering in the job.
