“Every year, electronics get faster, smaller, and cheaper.”
– Anyone Paying Attention
You don’t have to be an expert in electronics to see the power of the irresistible forces: Faster, Smaller, and Cheaper. Each one creates a variety of potential opportunities for our industry. As chips get more powerful, most boards have shrunk and are now manufactured in panels of 8, 12, or 20.
The semiconductor test industry moved to ‘multi-site’ testing over a decade ago because the number of die on a wafer began to increase into the thousands. By testing more die in parallel, the overall tester throughput increased. This concept is the driving force behind our idea of testing of boards in parallel.
We first recognized this opportunity a dozen years ago when we introduced MultiWriter™, our On-Board Programming Technology. By programming an entire panel in parallel, CheckSum began delivering the fastest possible programming solution to our customers. Now, after programming a billion chips and handling panels of 100-up+, CheckSum is recognized as the innovator in gang programming.

Next, we developed MultiCore ICT. Simply put, CheckSum offers up to 4 ICT modules operating in parallel, both in line and non-inline, to test up to 4 boards simultaneously. For high volume manufacturers of panelized boards, MultiCore ICT continues to offer a major throughput advantage.
More recently, CheckSum introduced our newest development, Parallel Functional* Test. Like MultiWriter™, Parallel Functional Test has unlimited scalability architecture, testing a panel of 40 boards in the same time as testing one singulated board.
These three parallel testing solutions provide the opportunity for exponentially more efficient throughput.
Success in parallel testing requires more than just a tester. CheckSum’s is the only solution offering tester, fixture, program, and worldwide support. Our customers only make one call to find an expert, ask a question, fix an issue, or address new requirements.
Parallelism is at the core of CheckSum’s test philosophy. How many boards would you like to test in parallel?
