A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components making use of the copper (conductive path) which is made by etching copper clad. PCB is also called as printed Wired Board (PWB). The PCB Depaneler without component is raw PCB & PCB with component is called printed circuit board assembly it indicates 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 continue to be costly because of its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which has just one single 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 contains a lot more than 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 Past one is using for prototype creation of printed circuit board. Prototype PCB means the limited nos. of PCB which can be for R & D purpose of new product or modification of existing product. The cooper etching (Photo etching) method is widely is used by large PCB manufacturing Companies across world.
– Screen printing technique is cost saving, but it compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is tough to achieve with this particular method. But nonetheless some companies are employing this to manufacture 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 lot of time. But this technique is not really useful for mass creation of Printed Circuit Boards. Photo etching With all the here we will 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 during my region with competitive rates. Select one from their website. First I have to deliver the gerber files to him for quotation because We have to say few reasons for my requirement For example Flex PCB Punching, PCB finish copper, Masking, silk screen color (By default it is masking PISM green, silk is white), HAL, Lead free, Delivery time. If 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 lessen 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 accomplished in Cam department in the company or many service beuro are available which provide economical service 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 cost-effective Solution on the flip side you must increase salary, bonus & other great things about employee on regular basis. What Cam dept do after getting the consumer data? Cam dept. carefully studies the gerber data. If found any required missing file the consumer is informed immediately. When all information & info is received, the cam dept. starts the pre-engineering of the job.
