Functional Integration, Rack, Program, Electronics & Fixtures
These are equipment mainly thought of in the electronic maquila, which is the one that produces electronic cards that carry out some specific function such as a computer motherboard, a controller card for a washing machine or dryer, automotive cards such as the dashboard, the controller for cleaning windshield, window lift card, other consumer electronics industries such as refrigerator control cards, etc.
Checking electronic cards
In any of these and many other types of electronic cards, the factory has the need to verify that its card works correctly and to make this verification they ask us to manufacture a functional equipment that tests the correct functionality of the card.
Selection of the range of measuring instruments
For this purpose, the minimum information required is a test specification document that will indicate what you want to test and how it should be tested, it is based on this document that the Mexican Test Services engineering staff will select the range of instruments. of measurement, programmable or fixed AC or DC voltage sources, oscilloscopes, signal generators, etc., in general the list of instrumentation necessary to carry out the tests in a precise, stable and with good speed, said instruments must be of the industrial type that support workloads 24/7.
Electrical diagram of the product to be tested
The other document that we request from our client is the electrical diagram of the product to be tested to know precisely from the way to feed said card to the way to control and test it.
Developments of this nature normally consist of a Rack where all the instruments, structured cabling and industrial computer will be placed inside, a Fixture is placed on the rack (interface between the card under test and the electronics and instrumentation), the fixture can have action mechanical or pneumatic according to what is most indicated by the precision, resistance and durability required.
Manufacture of machines on design by Mexican Test Services
Mexican Test Develop a test program in a programming language that is suggested by the client or decided by Mexican Test, this decision is made by the client. Therefore, said program will be in charge of carrying out each test routine, it will also make the decision according to the parameters established in the specification document.
If the card passed or failed the tests, these results are saved in a file so that they can be consulted by the corresponding engineering areas. Likewise, the files form a database that can be consulted to give traceability to the tested cards.
Obtain reports by hour, day, week or month according to requirements
Reports can be obtained by hour, day, week or month according to the requirement made by the client. The tests always start by scanning the serial number of the unit to be tested, which allows us to save the test file by giving the name of the unit’s serial number to said file.
If the card passed or failed the tests, these results are saved in a file so that they can be consulted by the corresponding engineering areas. Likewise, the files form a database that can be consulted to give traceability to the tested cards.
