Abstract

The present invention provides a kind of offline method for confirming SMT attachment programs, belongs to attachment program making technical field, the present invention includes the following steps：1）Coordinate shelves delete no gauge outfit, then click A row, select data to dissect, use fixed width；2）The coordinate shelves in two faces are processed into canonical form, it is standby then to save as TXT documents；3）Using CAM350 import corresponding to Gerber file；4）The coordinate that step 2 has been handled well imports, and 274x forms are fixedly installed with gerber is imported in method, new layer occurs after importing coordinate shelves, i.e. the new layer decode that the layer of coordinate shelves typically imports is 10；5）Part mounting coordinates will be embodied on Gerber files with the black circle of a yellow, manual confirmation yellow round dot whether part silk-screen geometric center i.e. can determine whether mounting coordinates correct.Processing technology level is improved, improves technologist's operating efficiency.

Description

A kind of offline method for confirming SMT attachment programs

Technical field

The present invention relates to attachment program making technology, more particularly to a kind of offline method for confirming SMT attachment programs.

Background technology

Electronic product need to undergo multiple links from product realization is designed into, and wherein electronic product machining is wherein important ring Section, SMT is surface installation technique（Surface Mounted Technology abbreviation）, be in current electronic assembly industry most Popular a kind of technology and technique.In order to realize the automatic attachment of electronic original part, technologist is needed to work out attachment before processing Program, with reach tell chip mounter how by design requirement paster purpose

The mounting position coordinate of electronic component is obtained during attachment program making, the acquisition modes of mounting coordinates are divided at present Two major classes, one kind be from designer or Customer Acquisition (design source file has higher security requirements), another be from The design coordinate of part is exported in design original and corresponding both the above scheme is matched with Gerber file in attachment journey Sequence is confirmed that often program making staffing mounts program to the whether accurate of coordinate well in advance without effective ways before completing Just find that part coordinate is incorrect afterwards, or just to adjust machine process to find such different by part process paster machine equipment personnel by PCBA Reason condition.

If above-mentioned exception is not found in advance, gently then cause programmer to check again and work out attachment program, cause work It is multiplied as amount;It is heavy then cause board processing progress to be delayed, or even cause circuit board fabrication plan to cancel, cost is high.

The content of the invention

In order to solve the above technical problems, the present invention proposes a kind of offline method for confirming SMT attachment programs.Towards work Factory is actually needed, and lifts processing technology level, lifting process person works' efficiency.

The technical scheme is that：

A kind of offline method for confirming SMT attachment programs, including

1）Coordinate document process:Coordinate format is necessary for 7 integers, and maximum number prefix number must be not zero；

2）Coordinate document imports Gerber file:Gerber is imported, 274x forms are fixedly installed;Occur newly after entering coordinate shelves The new layer decode that the layer of layer, i.e. coordinate shelves imports is 10；

3）Coordinate confirms:Handled more than, part mounting coordinates will be embodied in Gerber files with a black circle On, manual confirmation round dot whether part silk-screen geometric center i.e. can determine whether mounting coordinates correct.

Specifically comprise the following steps：

1）Coordinate shelves (client is exported or exported using design software) delete no gauge outfit, then click A row, select data Dissect, use fixed width;

2）The coordinate shelves in two faces are processed into canonical form, then save as the standby coordinate formats of TXT documents be necessary for 7 it is whole Number, and maximum number prefix number must be not zero, for example, maximum number be 123456 X Y all must simultaneously * 10, make dominant bit First numeral is not zero

3）Using Gerber file, the part housing layer that need to only show, generic name assembly_ corresponding to CAM350 importings Bot (top) or comp*_bot (top);Silk-screen layer generic name ref_a (b) or sst (ssb);

4）Coordinate step 2 handled well imports, and 274x forms are fixedly installed with gerber is imported in method, import and sit New layer occurs after mark shelves, i.e. the new layer decode that the layer of coordinate shelves typically imports is 10;

5）Handled more than, part mounting coordinates will be embodied on Gerber files with the black circle of a yellow, manually Confirm whether yellow round dot in the geometric center of part silk-screen can determine whether the whether correct of mounting coordinates

The beneficial effects of the invention are as follows

The present invention prepares difficult point from SMT processing technologys, with reference to a variety of CAD/CAM software features, proposes that one kind can for SMT The method of manufacturing and actual processing improved efficiency.The Failure count of reaching the standard grade of the invention for effectively reducing paster program, shortens product Exploitation and performance period, save new-products development expense.

Embodiment

More detailed elaboration is carried out to present disclosure below：

A kind of offline method for confirming SMT attachment programs of the present invention, comprises the following steps：

A. coordinate shelves (client is exported or exported using design software) delete 1 ~ 4 row shown in no gauge outfit figure, Ran Houdian Select A to arrange, select data to dissect, use fixed width；

B. the coordinate shelves in two faces are processed into following canonical form, it is standby then saves as TXT documents；

Coordinate format is necessary for 7 integers, and maximum number prefix number must be not zero, such as maximum number is 123456 X Y all must simultaneously * 10, dominant bit head numerals is not zero；

C. using Gerber file, the part housing layer that need to only show, generic name assembly_ corresponding to CAM350 importings Bot (top) or comp*_bot (top);Silk-screen layer generic name ref_a (b) or sst (ssb)；

D. coordinate step b handled well imports, and method is fixedly installed 274x forms, clicked here with gerber is imported The setting dialog box of appearance is set according to pattern；

New layer occurs after importing coordinate shelves, i.e. the new layer decode that the layer of coordinate shelves typically imports is 10, can be selected successively Tables-Apertures sets shapes and sizes respectively.

E. being handled more than, part mounting coordinates will be embodied on Gerber files with the black circle of a yellow, Manual confirmation yellow round dot whether part silk-screen geometric center i.e. can determine whether mounting coordinates correct.

Claims

A kind of 1. offline method for confirming SMT attachment programs, it is characterised in that including

1）Coordinate document process:Coordinate format is necessary for 7 integers, and maximum number prefix number must be not zero；

2）Coordinate document imports Gerber file:Gerber is imported, 274x forms are fixedly installed；Occur newly after entering coordinate shelves The new layer decode that the layer of layer, i.e. coordinate shelves imports is 10；

3）Coordinate confirms:Handled more than, part mounting coordinates will be embodied in Gerber files with a black circle On, manual confirmation round dot whether part silk-screen geometric center i.e. can determine whether mounting coordinates correct.
2. according to the method for claim 1, it is characterised in that
