3mil Fr4 Multilayer PCB Printed Circuit Board RoHS 94V0 Prototype

The puzzle
PCB design is completed because the PCB board shape is too small to meet the

production process requirements, or a product is composed of several pieces of PCB, so

it is necessary to assemble several small boards into a large board with an area that

meets the production requirements, or assemble several PCBs used for a product to

facilitate production and installation.The former is similar to the stamp plate, which

can not only meet the PCB production process conditions but also facilitate the

installation of components and components, and then separate when used, which is very

convenient.The latter is a product of a number of sets of PCB board assembled

together, so easy to produce, but also easy to a product together, clear.

2. Data generation
PCB board production is based on the film plate.Early production of film base plate,

the first need to produce a film base map, and then use the base map for photography

or copy.The accuracy of the base drawing must be consistent with that required by the

printed board, and consideration should be given to compensating for deviations caused

by the production process.The base drawing may be provided by the customer or made by

the manufacturer, but both parties shall cooperate and negotiate closely to make it

meet the requirements of the user and adapt to the production conditions.If the user

provides the base drawing, the manufacturer shall examine and approve the base

drawing, and the user may evaluate and approve the original or the first printed board

product.Base drawing methods include hand drawing, mapping and CAD drawing.With the

development of computer technology, the CAD technology of printed board has made great

progress, and the production technology of printed board has been rapidly improved to

the direction of multi-layer, thin wire, small aperture and high density. The original

film plate making technology has been unable to meet the design needs of printed

board, so the light drawing technology appeared.Using the light drawing machine can

directly send the CAD designed PCB graphics data files into the computer system of the

light drawing machine and control the light drawing machine to draw graphics directly

on the negative film.Then after developing, fixing to get the film base.The film base

plate made by light drawing technology has the advantages of high speed, high

precision and good quality, and avoids the possible human error when manual mapping or

drawing the base map, which greatly improves the working efficiency and shortens the

production cycle of the printed board.Laser light drawing machine, in a very short

period of time can complete the past many people can finish the work for a long time,

and its drawing of thin wire, high density plate is also incomparable to manual

operation.According to different structures of laser light drawing machines, they can

be divided into flat type, Internal Drum type and External Drum type.The standard data

format used by light drawing machine is GERBER-RS274 format, which is also the

standard data format of printed board design and production industry.The name of the

Gerber format is referenced from the pioneer of the design and production of light

drawing machine - Gerber Corporation in the United States.The generation of optical

drawing data refers to the transformation of design data generated by CAD software

into optical drawing data (mostly Gerber data), which is modified and edited by CAM

system to complete optical drawing preprocessing (plate-making, mirroring, etc.) so as

to meet the requirements of printed board production process.Then, the processed data

is sent to the optical drawing machine and converted into grating data by the Raster

image data processor of the optical drawing machine. The grating data is sent to the

laser optical drawing machine through the high-power rapid compression and reduction

algorithm to complete the optical drawing.

3, light drawing data format
The data format of optical drawing is based on Gerber data of vector optical drawing

machine, and the data format of vector optical drawing machine is extended, and it is

compatible with HPGL HP plotter format, AutoCAD DXF, TIFF and other special and

general graphics data formats.Some CAD and CAM developers are also extending the

Gerber data.
Here's a quick overview of Gerber's data.The official name for Gerber data is the

Gerber RS-274 format.Each symbol on the CODE plate of the vector optical drawing

machine has a corresponding D-code in the Gerber data.In this way, the light drawing

machine can control and select the code disk through the D code, and draw the

corresponding graphics.List the shape and size of D code and the symbol corresponding

to D code, that is, get a D code table.This D code table becomes a bridge from CAD

design to light drawing machine to use this data for light drawing.The user must

provide the corresponding D-code table with the Gerber optograph data.In this way, the

light drawing machine can determine according to the D code table which symbol disc

should be selected for exposure, so as to draw the correct graph.In a D code table, it

should generally include D code, the shape and size of each D code corresponding to

the code plate, as well as the exposure mode of the code plate.
