Achieve Test Excellence
TESLENCE was founded by a group of dedicated engineers in production semiconductor testing from OSAT (Outsourced Semiconductor Assembly Test), ATE (Automated Test Equipment) suppliers, probe hardware suppliers, and IC design companies. Our team members have experience supporting production test activities and understand how production challenges can be underestimated resulting in unnecessary risk and cost during product launches and volume production phases. TESLENCE was founded to dedicate our expertise in the test industry to support production issues from data analysis, test time reduction, yield improvement, hardware optimization, and production automation. We dedicate ourselves to provide a timely solution to all your test production issues!

PRODUCTION FLOW AUTOMATION
In a production environment, many things are needed to maintain continuous testing and material flow. These include but are not limited to: setting up hardware, performing correlation runs, managing system downtime, data review and material disposition. Each of these drain engineering resources and are often placed in queue to deal with more immediate needs. Our team can review your needs, suggest, and provide methods for automation to free up your engineering resources and enable a smoother production operation.
TEST PROGRAM OPTIMIZATION
Test program efficiency and stability is crucial for stable production. It can be a great target for enhancement. Our engineering team is very strong in this area. We are experienced in identifying sources for test time reduction and yield improvements on the production testfloor. We can help identify improvements without sacrificing product quality. We can help collect all data necessary to prove your test coverage remains intact or is improved to meet your goals.
HARDWARE REPAIR AND IMPROVEMENTS
Spare hardware is always a key factor in how smooth a production ramp will be. Too few spares can cause tester downtime due to scheduled and unscheduled hardware maintenance. Too many are an unnecessary expense. Our team is experienced supporting a variety of hardware technologies and can support them on-site to get you back in production.
SOFTWARE TOOL DEVELOPMENT
In engineering and production phases, special handling requirements are common. This can include custom data processing, material control, production special flow handling, etc... We can help develop tools to support your needs!
ON-SITE NEW EQUIPMENT CHECK-OUT AND PERFORMANCE EVALUATION
Teslence personnel can be on-site for evaluation and bring-up of equipment and first- level troubleshooting. We are experienced working with a wide range of test and equipment vendors and troubleshooting directly on the test floors. Teslence can provide guidance for evaluation, gather data, performance analysis, and troubleshooting to support a thorough engineering evaluation.
If you are looking for improvement ideas, our team is happy to review and provide enhancement opportunities for your production needs. If you already have ideas, we'll do our best to help you implement it!
Test throughput can often be a source of misunderstanding between IC company and the subcon manufacturer. Test time is not the only factor that affects throughput. Many other factors such as equipment stability, OEE, site-site performance deltas, stepping and retest effectiveness, contact optimization, etc are also affecting your throughput. Our team is strong in this field and can help you meet your shipment demand.
PRODUCTION LINE DATA ANALYSIS
While there are numerous data analysis tools on the market, most of them are designed for fab and device data. Analysis of production performance data requires a very different focus from fab. We can help setup your data stream, database, and create a customized dashboard for your preferred metrics display.
