Techniques Enrico Marcelo Uses:
Circuit Design, Research, Schematic diagram reading and understanding, Circuit Re design and improvement.
Enrico Marcelo's Problem Solving Skills:
- Digital Circuit Design
- Debugging and board level repair.
- Reverse Engineering
Enrico Marcelo's Problem Solving Experience:
- RF mechanical Switch replaced regularly in the testers that cost more than $ 4 Million per Fiscal Year for maintenance expenses- solution I provided is I developed a method and process to refurbish the used RF mechanical Switch that completely eliminated the inevitable expenses.
- I redesigned the program board of old AEHR Burn In Test Equipment to meet the current device dynamic life test specifications.
- I designed and implemented a Solid State Switches in replacement of RF mechanical Switches- for Cost Savings, Longer Life Span and low equipment MTBF purposes.
- I redesigned an existing Test Equipment board " 8 CH analog Card with Current Reading Board" that always fail - Micro controller breakdown or program runaway.
- I fixed a major issue on LIFE Test Burn-In process by re correcting the design of the Dynamic Burn In boards to prevent the FPGA device burning during Life test.
