Commissioning of prototypes

Do you repeatedly experience problems when commissioning your prototypes?

 

The increasing shortage of skilled workers combined with time sensitive deadlines mean that almost no developer can afford to waste time when validating prototypes.

Often firmware for the new board design is not ready or simply not yet error-free. We will show you how you can quickly check your hardware for soldering and assembly errors, and save an average of two weeks per project on troubleshooting.

Pin-level fault diagnosis

You have a faulty electronics assembly – how quickly can you find the root cause?

 

To check whether a board is functioning correctly, a functional or end-of-line test is usually implemented at the end of the production line. The aim is not to find failures, but to ensure that there aren’t any.  This is because if the failure is found here, it is usually expensive and very time-consuming to repair. We will show you how to locate a hardware failure with pin-level accuracy in just a few seconds.

Programming and testing

Electrical testing combined with lightning-fast programming!

 

With ever-increasing amounts of data and rising costs for test and programming fixtures, it makes sense to combine electrical testing with programming. The latter is, of course, only carried out after a PASS test, and a combined test and programming station is desirable.

Efficient prototype commissioning with the SCANFLEX Board Grabber

Do you often wish you had a third hand? Universal board fixture with the option to hold manually placed probes.

 

Particularly when validating prototypes or testing small lots of boards, a bed-of-nail adapter is often not available for cost reasons. Our Board Grabber can solve this problem effectively.

Application example: HANZA Beyers GmbH

The electrical test with the JTAG/Boundary Scan

HANZA Beyers GmbH is a medium-sized contract manufacturer, based in Mönchengladbach. The company works on behalf of OEM customers from the telecommunications , medical and building technology sectors. There are increasing enquiries from the fields of Intelligent electronics for Industry 4.0 and Smart Home applications. From Pilot Series and Prototypes to batch sizes of 50,000, the production scales flexibly and also implements demanding technological customer requirements.


Challenge

  • in some cases customers require an error tolerance of <1%
  • difficult testability due to high use of BGA and missing test points
  • supplement to In-Circuit Test  necessary
  • compliance with Cycle rates

Our Solution

Production Tester JULIET

  • combination of test strategies for almost 100% test depth
  • quick adaptation of test subjects
  • test system in combination with automatic component group progamming to save time
  • fully automatic programming of all ICs directly integrated in the test process

英飞凌应用实例

使用VarioTAP测试和编程英飞凌汽车电源IC

最新一代英飞凌Infineon AURIX MultiCore装置以及汽车和嵌入式电源领域的TLE987x系列产品特别适用于以下控制应用:

 

  • 燃油泵
  • HVAC鼓风机系统
  • 基于传感器的电机控制
  • 安全关键性应用

 


挑战

BGA或VQFN-48封装节省空间,但通常不允许与外部仪器直接接触。

 

 

我们的解决方案

VarioTAP通过其测试结构提供对内置资源的访问。可以生成静态和动态测试图案,也可以与其他测试方法(例如边界扫描)结合使用。因此扩大了结构测试,首先可以进行功能和诊断测试。
