Quality Assurance
Second is to maximize the arrangement of heat dissipation by system design. WEBS systems are designed with
an all-aluminum chassis that is ideal for heat dissipation. Heat sinks link the ICs on the embedded board and the
aluminum chassis for direct heat transference. The heat transfers from the bottom up so the lower temperature
is at the chassis top for greater ease of use and protection. The pictures below illustrate the heat low of a WEBS
system. Balancing the heat of the product in this way makes the perfect fan-less system.

3 Thermal Validation
After completing the thermal design, the WEBS system undergoes thermal validation by following Intel’s thermal
guide. The system is tested inside the calibrated chamber with deined temperatures. The eficacy of the WEBS
system is further improved when the temperature of any component is over speciication. Thermal tests are
conducted until all the major ICs are below thermal speciication.
Holes are made on the heat sink and thermal sensor cables are added for measuring the temperature
4 Safety & Reliability Validation
In addition to the thermal validation, the WEBS systems undergo safety assessment and tests and achieve CE and
FCC certiication. Testing includes ESD, EMI and EMC.
To ensure product quality, complete quality assurance tests are performed during both the development and the
manufacturing phases for all system-level products. Portwell WEBS systems are tested and comply with safety
regulations, and are reliable to be used in the harsh environments.
-Based on customer’s requirements, Portwell can do additional tests with a NRE (non-recurring engineering) charge.
