A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components making use of the copper (conductive path) which can be produced by etching copper clad. PCB is additionally called as printed Wired Board (PWB). The PCB Separator 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 will still be costly due to its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which contains just one single track (copper) layer is known as SSB. Double Sided Board (DSB) The Printed Circuit Board that has two track (copper) layer is referred to as DSB. Multi layer Board The Printed Circuit Board which contains over 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 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 purpose of new product or modification of existing product. The cooper etching (Photo etching) way is widely is used by large scale PCB manufacturing Companies throughout world.
– Screen printing strategy is cost saving, however it compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is very hard to achieve using this method. But nevertheless 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 technique is just not useful for mass creation of Printed Circuit Boards. Photo etching Using the below we will look the steps involved for Printed Circuit Board manufacturing with photo Etching methods.
Let’s start from beginning 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 have got to deliver the gerber files to him for quotation in this I have to mention few aspects of my requirement Such as PCB Punching, PCB finish copper, Masking, silk screen color (Automatically it can be masking PISM green, silk is white), HAL, Lead free, Delivery time. Once this data reach to Printed Circuit Board manufacturer he studies the info & gives the quotation. Following are Factors pcbflex play vital role deciding the cost of 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 Depaneling Router is true of pre-engineering of gerber data. This is done in Cam department from the company or many service beuro are offered which offer cost effective company to Printed Circuit Boards Industry.
Why service beuro? Saves expense on OEM license cost Saves expense on Salary, bonus & other benefits of Employee. Even the service beuro provide economical Solution on the other hand you must increase salary, bonus & other great things about employee on consistent basis. What Cam dept do once you have the customer data? Cam dept. carefully studies the gerber data. If found any required missing file the individual is informed immediately. When information & information is received, the cam dept. starts the pre-engineering of the job.
