A Printed Circuit Board or PCB is Mechanical Support & electrically wired the electronic components utilizing the copper (conductive path) which happens to be manufactured by etching copper clad. PCB is additionally known 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 highly affordable especially Single sided Board (SSB) & Double Sided Board (DSB). Multi layers PCB remain costly due to the high setup charges. Single Sided Board (SSB) The Printed Circuit Board which includes just one track (copper) layer is named SSB. Double Sided Board (DSB) The Printed Circuit Board which contains two track (copper) layer is known as DSB. Multi layer Board The Printed Circuit Board which has a lot more than two copper layers. Materials Used for Printed Circuit Board (PCB) Conductive Layer is actually is of thin copper foil the base is of glass epoxy (insulating materials) some types are as below.
– The Last the initial one is using for prototype creation of printed circuit board. Prototype PCB means the limited nos. of PCB which is for R & D intent behind cool product or modification of existing product. The cooper etching (Photo etching) strategy is widely is used by large PCB manufacturing Companies all over 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 very difficult to achieve using this method. But still some companies are using 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 considerable time. But this technique will not be helpful for mass manufacturing of Printed Circuit Boards. Photo etching With the below we will appear 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 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 store. First I have to send the gerber files to him for quotation because I have to bring up few reasons for having my requirement Including Die Tooling, PCB finish copper, Masking, silk screen color (Automatically it is actually masking PISM green, silk is white), HAL, Lead free, Delivery time. If this data reach to Printed Circuit Board manufacturer he studies the data & gives 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 lessen 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 are available which offer cost effective 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 other hand you must increase salary, bonus & other advantages of employee on regular basis. What Cam dept do once you have 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.
