Large Thermal Shock Chambers

Detect product defects before they reach your customer

Vertical Thermal Shock chambers consist of two separately controlled hot and cold zones. Product is transferred between these zones for rapid product temperature changes. Thermal Shock Chambers are designed to perform tailored environmental stress screening of component and board level electronic assemblies. The return on investment in both actual savings and customer confidence adds greatly to the value of electronic assemblies screened in a CSZ thermal shock system.

Chambers meet the unique requirements of the following specifications: JESD22-A104 | MIL-STD 883, Method 1010.8 | MIL-STD 202, Method 107G |  MIL-STD 810, Method 503.5. The cold chamber zone will also perform as a fully functional, independent environmental test chamber increasing the value of your investment.

Touch Screen Controller
  • CSZ EZT-570 Touch Screen Controller is designed to save chamber programming and setup time. Standard features data logging, data file access via memory stick or PC, Ethernet control and monitoring, alarm notification via email or phone text message, full system security, online help & voice assistance in multiple languages and more.
  • A Temperature Limit and alarm is included to protect your product.
EZ-View Software
  • RS-232/485 serial communications, Ethernet control and monitoring offer a selection of communications options.
  • EZ-View optional software allows user to control and monitor up to 20 chambers from any location.
Large Thermal Shock Basket
  • Rapid airflow through the workspace. This is the cornerstone to successful performance of MIL-STD 883G, Method 1010.8 (Test Condition C) and for Environmental Stress Screening. Provides an average of 500 feet per minute air velocity over the devices under test to facilitate fast part temperature change rates
  • Door safety feature prevents the transfer basket from moving when door is opened.
  • A fog-free viewing window and interior light to view product under test
  • All liners are constructed from Type 304 brushed stainless steel that is easy to clean. All seams are continuously welded to form a hermetically sealed unit to prevent moisture migration.
  • The chamber exterior is constructed of formed sheet steel for structural strength and finished with a durable powder coat finish or textured polyurethane paint.
Large VTS Refrigeration
  • Pressure gauges allow operating pressures to be continuously monitored and provide early warning indicators.
  • CSZ test chambers utilize refrigerants which are environmentally safe, non-flammable, non-explosive and have a Zero Ozone Depletion Potential (ODP).
