Leak test system for TIPM PCB assembly : ระบบทดสอบรอยรั่วสำหรับ TIPM PCB


Problem/Goal:
Customer required a system to peform pressure decay leak tests on a TIPM PCB assembly.

TME เครื่องตรวจวัดรอยรั่วที่เป็นที่รู้จักในด้านความสามารถในการออกแบบ และผลิตเครื่องมืออุปกรณ์ติดตั้ง เพื่อแก้ปัญหาการทดสอบเฉพาะ ผลิตภัณฑ์ยานยนต์มีข้อกำหนดในการทดสอบ และการจัดการที่หลากหลาย D1368 เรายินดีให้คำปรึกษาทุกขั้นตอน


Resolution:
TME created a test system with a custom test fixture connected to the TME Solution. A test item is properly placed into the test fixture, and the system automatically performs a leak test by pressurizing the PCB assembly through the center connector cavity with the two other connector cavities blocked with a seal from clamping cylinders.

The leak test is performed using the test parameters entered. Results of the test are repoƒed to the operator with visual and audible indicators (audible for reject only)  and are recorded in the Datalog on the TME Solution.

Paƒrts that “PASS” the test are automatically marked on the side wall of the assembly with a white ink dot.  

Th€e operator removes ‘good’ partƒs by simply raising the safety door and removing the part

Reject paƒrts are not marked and will be locked in the fixture and must be manually removed from the system by pressing the “STOP” buŽtton on the instrument in order to ensure separation of good and reject partƒs by the operator.  A second press of the “STOP” buttŽon must be made to reset the instrument to the “READY” state for the next test.  

A magnetic switch safety interlock has been provided along with fixture guards to prevent possible pinch points from being accessible.  An ESD ground cable prevents static build up on the fixture.  

Fixtures:
TME is known for its ability to design, and manufacture special instrument and fixture solutions to solve specific testing problems.

Automotive products present a variety of testing, sealing and handling requirements including marking, locking and multiple test procedures.

 

 

TM Electronics offers two instrument choices:€There are subtle differences between to the two instruments. Your TME account manager will recommend which will best fit your testing needs.

TME Solution: € The TME Solution has proven throughout the years to be a most reliable long lasting custom and standard leak test instrument.

Sensitive, repeatable, easily maintainable and reliable, the TME Solution can perform a variety of test types on product, including burst, occlusion, vacuum and pressure decay, crack, and differential pressure or vacuum.

Its touch screen menu driven operation allows the operator to control the test parameters, examine statistical analysis of results and download files easily.

TME Worker Integra:
A bench-top, high resolution leak test instrument with small foot print and user-friendly ease of operation. €

The icon based touchscreen display provides easy, clear navigation through the wide variety of data handling and review screen.

Pressure changes as low as 0.0001 psi are detected from leaks in test paƒrts.
