A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components making use of the copper (conductive path) which happens to be manufactured by etching copper clad. PCB is also called as printed Wired Board (PWB). The PCB Separator without component is raw PCB & PCB with component is named printed circuit board assembly it indicates 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 the high setup charges. Single Sided Board (SSB) The Printed Circuit Board which includes just one track (copper) layer is known as SSB. Double Sided Board (DSB) The Printed Circuit Board which has two track (copper) layer is called DSB. Multi layer Board The Printed Circuit Board which includes over two copper layers. Material 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 Final one is using for prototype manufacture of printed circuit board. Prototype PCB means the limited nos. of PCB which can be for R & D intent behind new product or modification of existing product. The cooper etching (Photo etching) technique is widely can be used by large PCB manufacturing Companies all over world.
– Screen printing technique is cost saving, nevertheless it compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is tough to achieve using this method. Yet still some companies use 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 methods save great deal of time. But this procedure is not a good choice for mass production of Printed Circuit Boards. Photo etching With all 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 manufactured. Suppose We have requirement of Printed Circuit Board I will search the Printed Circuit manufacturer within my region with competitive rates. Select one from their store. First I have to transmit the gerber files to him for quotation because We have to say few aspects of my requirement For example 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 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 PCB Router Machine applies to pre-engineering of gerber data. This is accomplished in Cam department of the company or many service beuro are offered that provide cost effective 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 alternatively you will need to increase salary, bonus & other great things about employee on regular basis. What Cam dept do after getting the customer data? Cam dept. carefully studies the gerber data. If found any required missing file the individual is informed immediately. When all information & info is received, the cam dept. starts the pre-engineering from the job.
