A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components while using copper (conductive path) which happens to be manufactured by etching copper clad. PCB is also known as printed Wired Board (PWB). The PCB Depaneler without component is raw PCB & PCB with component is referred to as printed circuit board assembly this 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 due to its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which contains merely one track (copper) layer is known as SSB. Double Sided Board (DSB) The Printed Circuit Board which has two track (copper) layer is known as DSB. Multi layer Board The Printed Circuit Board that has greater than two copper layers. Materials 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 Past 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 reason for new product or modification of existing product. The cooper etching (Photo etching) strategy is widely is commonly used by massive PCB manufacturing Companies across world.
– Screen printing strategy 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 particular method. But still some companies are using 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 methods save lot of time. But this technique is not really a good choice for mass creation of Printed Circuit Boards. Photo etching Together with the here we can look the steps involved for Printed Circuit Board manufacturing with photo Etching methods.
Let’s start from beginning how the Printed Circuit Boards are made. Suppose I actually have requirement of Printed Circuit Board I will search the Printed Circuit manufacturer inside my region with competitive rates. Select one from their website. First I have to transmit the gerber files to him for quotation for the reason that I have to bring up few reasons for having my requirement For example Flex PCB Punching, PCB finish copper, Masking, silk screen color (Automatically it is actually masking PISM green, silk is white), HAL, Lead free, Delivery time. When this data reach to Printed Circuit Board manufacturer he studies the information & 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 minimize cost) Always verify the output (gerber data) before sending it to manufacturer.
After accepting quotation the PCB Router Machine goes for pre-engineering of gerber data. This is done in Cam department of your company or many service beuro can be found that provide affordable 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 cost effective Solution alternatively you must increase salary, bonus & other benefits associated with employee on regular 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 & data is received, the cam dept. starts the pre-engineering of your job.
