Electronics Manufacturing Instruments

Time and temperature are very important variables in soldering printed circuit boards. It is important to bring the circuit board assemblies up to a high enough temperature for a long enough period to effectively solder the components to the board. Getting the temperature up too high or heating the assembly too quickly can result in component damage. Not heating things up enough results in poor soldering and reliability problems.
ECD manufactures a variety of instruments to assist you in accurately monitoring the time and temperature variables in your electronics manufacturing processes.

ECD is proud to introduce OvenWATCH, the newest member of our family of quality management tools for the automated solder process. OvenWATCH is designed to continuously monitor the quality of PCB assemblies as they pass through your reflow solder machines. Now OvenWATCH can provide you and your customers with the confidence of knowing that the quality of your PCB assemblies is being monitored 24 hours per day…..365 days per year.

Continuous 24-hr product quality monitoring
Board dynamic profile generation without attaching thermocouples
Automatic SPC Analysis & Alert Reporting
Archiving of the dynamic profile of each pcb processed
Remote alarm capability for off-site troubleshooting
Provides board-level dynamic profile traceability
Provides your customers with proof of your product quality

Reduce Costs
OvenWATCH allows one operator to manage multiple reflow ovens
OvenWATCH reduces setup time and change over time
OvenWATCH reduces scrap rate and rework while increasing yields and production rates

Increased Process Control
OvenWATCH continuously monitors the quality of PCB assemblies passing through your reflow solder oven….24 hours a day….365 days a year
OvenWATCH creates a board-specific dynamic thermal profile without the need to connect thermocouple sensors
OvenWATCH automatically reports any out-of-specification problems & trends before PCB quality is negatively affected
OvenWATCH can provide your customers with the confidence of knowing that you are monitoring the quality of their products 24 hours per day

Improve Quality and Product Yield
OvenWATCH continuously monitors the process 24 hours a day
OvenWATCH automatically utilizes statistical process control (SPC) software to establish quality specifications & report out-of-control trends
OvenWATCH reports out-of-control trends by alarm lamp, e-mail, or page alert message

Improve Record keeping
OvenWATCH archives, for later review, the dynamic profile of each PCB assembly processed
OvenWATCH records all events that the machine and / or the assemblies experience
OvenWATCH's In & out board sensors and bar code reading system provide individual PCB assembly profile tracking
