A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components using the copper (conductive path) which is manufactured by etching copper clad. PCB can also be known as printed Wired Board (PWB). The PCB Separator without component is raw PCB & PCB with component is known as printed circuit board assembly it implies 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 due to its high setup charges. Single Sided Board (SSB) The Printed Circuit Board which has just one track (copper) layer is referred to as SSB. Double Sided Board (DSB) The Printed Circuit Board which has two track (copper) layer is named 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 Final the initial one is using for prototype creation 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) strategy is widely is used by large PCB manufacturing Companies around world.
– Screen printing way is cost saving, however it compromise with quality. Also fine Printed Circuit Board with below 10 mil track & same spacing is tough to achieve with this method. But still some companies use this to produce 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 time. But this method is just not a good choice for mass creation of Printed Circuit Boards. Photo etching Using the below we will appear the steps involved for Printed Circuit Board manufacturing with photo Etching methods.
Let’s start from beginning exactly how the Printed Circuit Boards are made. Suppose I have requirement of Printed Circuit Board I am going to search the Printed Circuit manufacturer in my region with competitive rates. Select one from them. First I have to transmit the gerber files to him for quotation for the reason that I have to say few reasons for having my requirement Including Flex PCB Punching, PCB finish copper, Masking, silk screen color (By default it can be masking PISM green, silk is white), HAL, Lead free, Delivery time. If this data reach to Printed Circuit Board manufacturer he studies the info & 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 Depaneling Router applies to pre-engineering of gerber data. This can be done in Cam department from the company or many service beuro can be found which offer economical service to Printed Circuit Boards Industry.
Why service beuro? Saves expense on OEM license cost Saves expense on Salary, bonus & other advantages of Employee. Even the service beuro provide economical Solution alternatively you must increase salary, bonus & other great things about employee on consistent 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 information & info is received, the cam dept. starts the pre-engineering in the job.
