A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components while using copper (conductive path) that is produced by etching copper clad. PCB can also be known as printed Wired Board (PWB). The PCB Separator 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 because of its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which has just one track (copper) layer is named SSB. Double Sided Board (DSB) The Printed Circuit Board that has two track (copper) layer is named DSB. Multi layer Board The Printed Circuit Board which includes more than two copper layers. Material Used for Printed Circuit Board (PCB) Conductive Layer is simply is of thin copper foil the base is of glass epoxy (insulating materials) some types are as below.
– The Final the first is using for prototype manufacturing of printed circuit board. Prototype PCB means the limited nos. of PCB which happens to be for R & D function of cool product or modification of existing product. The cooper etching (Photo etching) way is widely is utilized by large PCB manufacturing Companies all over world.
– Screen printing strategy is cost saving, but it really compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is very hard to achieve using this type of method. But still 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 lot of time. But this method is not useful for mass manufacture of Printed Circuit Boards. Photo etching Together with the here we will appear the steps involved for Printed Circuit Board manufacturing with photo Etching methods.
Let’s start from beginning the way the Printed Circuit Boards are made. Suppose I actually have requirement of Printed Circuit Board I will search the Printed Circuit manufacturer in my region with competitive rates. Select one from them. First I have to send the gerber files to him for quotation for the reason that I have to note few things about my requirement Including 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 the information & affords the quotation. Following are Factors pcbflex play vital role deciding the buying 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 lower cost) Always verify the output (gerber data) before sending it to manufacturer.
After accepting quotation the PCB Depaneling Router applies to pre-engineering of gerber data. This can be done in Cam department from the company or many service beuro can be purchased which 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. Also the service beuro provide economical Solution on the other hand you will need to increase salary, bonus & other benefits of employee on consistent basis. What Cam dept do after getting the customer 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 of your job.
