A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components using the copper (conductive path) which is produced by etching copper clad. PCB is likewise called as printed Wired Board (PWB). The PCB Separator without component is raw PCB & PCB with component is known as printed circuit board assembly it implies 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 due to its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which includes just one track (copper) layer is referred to as SSB. Double Sided Board (DSB) The Printed Circuit Board which includes two track (copper) layer is called DSB. Multi layer Board The Printed Circuit Board which contains greater 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 Last the initial one is using for prototype manufacturing of printed circuit board. Prototype PCB means the limited nos. of PCB that is for R & D intent behind new product or modification of existing product. The cooper etching (Photo etching) technique is widely is used by large scale PCB manufacturing Companies across 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 hard to achieve with this method. But nonetheless some companies use this to manufacture 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 lot of time. But this process is just not ideal 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 just how the Printed Circuit Boards are created. Suppose We have requirement of Printed Circuit Board I am going to search the Printed Circuit manufacturer in my region with competitive rates. Select one from them. First We have to send out the gerber files to him for quotation in that We have to note few things about my requirement Including Die Tooling, PCB finish copper, Masking, silk screen color (Automatically it 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 of 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 Online PCB Router is true of pre-engineering of gerber data. This is done in Cam department from the company or many service beuro can be purchased that provide economical service to Printed Circuit Boards Industry.
Why service beuro? Saves expense on OEM license cost Saves expense on Salary, bonus & other great things about Employee. Also the service beuro provide affordable Solution alternatively you must increase salary, bonus & other benefits associated with employee on consistent basis. What Cam dept do after getting the consumer data? Cam dept. carefully studies the gerber data. If found any required missing file the customer is informed immediately. When all information & data is received, the cam dept. starts the pre-engineering from the job.
