A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components while using copper (conductive path) that is created by etching copper clad. PCB is likewise called as printed Wired Board (PWB). The PCB Depaneler without component is raw PCB & PCB with component is referred to as 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 remain costly because of its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which has merely one track (copper) layer is referred to as SSB. Double Sided Board (DSB) The Printed Circuit Board that has two track (copper) layer is called DSB. Multi layer Board The Printed Circuit Board which contains a lot more 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 Last 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 can be used by massive PCB manufacturing Companies throughout world.
– Screen printing technique is cost saving, however it compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is very difficult 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 techniques save considerable amount of time. But this process is not a good choice for mass creation of Printed Circuit Boards. Photo etching With all the below we can look 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 inside my region with competitive rates. Select one from their store. First I actually have to send the gerber files to him for quotation because I have to say few aspects of my requirement For example 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 your data & provides 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 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 is done in Cam department in the company or many service beuro are available that provide affordable 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 alternatively you will need to increase salary, bonus & other great things about employee on regular basis. What Cam dept do after getting the client data? Cam dept. carefully studies the gerber data. If found any required missing file the individual is informed immediately. When information & information is received, the cam dept. starts the pre-engineering in the job.
