Printed circuit board level reliability test
Printed circuit board test is a service is for companies in need to test, verify or benchmark component reliability. The service can be utilised by companies having their own component design and manufacturing, or optionally by operators buying components for their own use.
Besides verification needs, Toptester BLR (Board Level Reliability) test services could be used also for R&D purposes.
Component Reliability Testing – Ensure Your Product Works Before Production
Reliability testing of a solderable surface mount device (SMD) ensures that your product will perform as designed throughout its entire life cycle. A single component failure, such as solder failure or material fatigue, can lead to the entire product failing.
Testing before production can identify critical weaknesses early on and ensure that the product can withstand the intended operating conditions. Toptester offers comprehensive component-level reliability testing in accredited laboratory conditions without the need for your own testing investments.
Why is component reliability testing critical?
In product development, attention is often focused on functionality, but in practice, product reliability is determined by the details: components, connections and materials. Without tested data, component durability is based on assumptions. Real risks are often only realized in the field, making repairs significantly more expensive.
Component reliability testing can:
- identify weaknesses in solder joints and connections
- assess the durability of materials under load
- ensure the functionality of components in real-world conditions
- reduce complaints and recalls
- support product development and certification
Testing turns uncertainty into measurable and reliable information.
Test before production to save costs
Component reliability testing is most effective when carried out before production starts. Changes made at this stage are significantly cheaper than repairs made during production or in the field.
When a product is already in production, correcting errors often leads to expensive recalls, redesigns and delivery delays. Testing provides a real picture of component performance in advance, which minimizes risks and supports a smooth transition to production.
Component-level testing with Toptester
Toptester offers a comprehensive service for component reliability testing. The test program is always designed for each product, taking into account the intended use, load conditions and market requirements.
We also offer a unique comprehensive service, where we design, manufacture and assemble test boards and carry out the actual testing and analysis. This significantly speeds up product development and frees up your organization’s resources for core competence.

Component reliability test methods
Component reliability testing simulates the loads that products encounter in practice. Testing can include combinations of temperature, humidity and mechanical stress.
Toptester performs, among other things:
- temperature cycle tests with humidity
- thermal shock tests
- drop tests up to 30,000 g load
- vibration tests up to 2000 Hz
- four-point bending tests with strain measurement
- X-ray transmission of small products
- making of cross-sections for fault finding
A single test method does not always reveal all weaknesses. Therefore, the test program is often built as a combination of several loads that correspond to the real operating environment.
Real-time measurement and failure analysis
In advanced tests, the behavior of components is monitored in real time during the load. The measurement data tells you exactly when a failure starts to develop and how it progresses.
Real-time measurement combined with testing and post-test failure analysis enable the identification of the root causes of failure. This information is critical for product development, as it enables targeted and cost-effective improvements to the structure.
Component testing according to standards
STANDARDS
Component reliability tests are carried out according to international standards so that the results are comparable and acceptable in different markets. Testing can be performed according to the following standards, for example:
- IEC
- JEDEC
- MIL-STD 883
- AEC
- customer’s own standard
Toptester is an accredited test house for several tests according to JEDEC standards.
Test equipment and capacity
Toptester has a wide range of testing capacity for component reliability testing. We use, among other things:
- several drop test equipment (Lansmont and Salon Teknopaja)
- thermal shock cabinets (Espec TSA-101S-W)
- vibration and mechanical testing equipment
- x-ray for product penetration
- equipment for cross-section of a product or component: making hie samples for circuit boards, solders and metal welds (penetration)
All testing is carried out under controlled laboratory conditions, which ensures the repeatability and reliability of the results.

FAQ – Frequently Asked Questions about Component Reliability Testing
What is measured in component reliability testing?
Testing evaluates the ability of components, connections and materials to withstand mechanical and environmental loads and to maintain their functionality during use.
Why are solder joints a critical test item?
Solder joints are often the weakest link in electronics. Temperature fluctuations and mechanical stress can cause micro-fractures that lead to malfunctions.
When should testing be performed in product development?
As early as possible before production. This way, weaknesses can be corrected cost-effectively before series production.
Can testing be tailored to the product?
Yes. The test program is designed based on the product’s intended use, materials and requirements.
What are the benefits of real-time measurement?
Real-time measurement enables more accurate analysis of failures and helps identify the time and cause of the failure.
Can a single test be sufficient?
Rarely. In real-world use, loads often occur simultaneously, so combining multiple tests gives a more realistic picture.
How quickly do you get test results?
Test results are typically available within a few days or weeks, depending on the scope of the test program.
Do you need your own testing equipment?
No. By outsourcing testing to Toptester, you avoid investing in equipment and gain access to expert expertise.
