A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components making use of the copper (conductive path) that 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 implies 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 for its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which contains just one track (copper) layer is known as SSB. Double Sided Board (DSB) The Printed Circuit Board which contains two track (copper) layer is referred to as DSB. Multi layer Board The Printed Circuit Board that has over two copper layers. Materials Used for Printed Circuit Board (PCB) Conductive Layer is essentially 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 manufacturing of printed circuit board. Prototype PCB means the limited nos. of PCB which can be for R & D function of cool product or modification of existing product. The cooper etching (Photo etching) technique is widely is commonly used by large scale 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 hard to achieve using this type of method. But still some companies use 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 techniques save lot of time. But this procedure will not be useful for mass production of Printed Circuit Boards. Photo etching Together with the below we will be the steps involved for Printed Circuit Board manufacturing with photo Etching methods.
Let’s start from beginning how the Printed Circuit Boards are created. Suppose I actually have requirement of Printed Circuit Board I am going to search the Printed Circuit manufacturer during my region with competitive rates. Select one from them. First I actually have to send out the gerber files to him for quotation for the reason that We have to mention few reasons for my requirement Including Die Tooling, PCB finish copper, Masking, silk screen color (By default it really is masking PISM green, silk is white), HAL, Lead free, Delivery time. Once this data reach to Printed Circuit Board manufacturer he studies the data & provides the quotation. Following are Factors pcbflex play vital role deciding the price tag on Printed Circuit Board. Quantity, Minimum track, spacing & minimum drill diameter (Keep minimum track thickness & spacing between two connection 6 to 8 mill to reduce 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 is done in Cam department of your company or many service beuro are offered which offer economical service to Printed Circuit Boards Industry.
Why service beuro? Saves expense on OEM license cost Saves expense on Salary, bonus & other benefits of Employee. Also the service beuro provide cost effective Solution on the flip side you have to increase salary, bonus & other benefits of 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 consumer is informed immediately. When all information & details are received, the cam dept. starts the pre-engineering from the job.
