How The Component Signal Is Reported
The Component Signal is a newsletter from POCONS USA covering the electronics component supply chain — pricing, allocation, lead times — and board-level EMI shielding design. This page explains how each issue is researched and sourced, so readers (and the people who cite us) know exactly what they are getting.
Who publishes it
POCONS USA is a US company headquartered in San Diego that supplies board-level EMI shielding — shield cans, SMT shield clips, precision spring contacts, and custom metal stampings — direct from the manufacturer. Our products are manufactured in Korea under IATF 16949. Because production sits in Korea, we follow the Asian electronic-component supply chain closely; this newsletter passes that read forward. It is edited by Mike Kwak, Director.
How issues are sourced
- Web-grounded. Each issue is researched against current public sources — trade bodies and indices (ICSG, WSTS, JEITA), market reporting, exchange and analyst data, and company disclosures.
- Every specific figure is attributed. A price, percentage, or date is tied inline to its source. A number we cannot source is cut, not guessed.
- Forecasts are labeled as forecasts. Projections are flagged as such, with the forecaster named, because forecasts carry revision risk.
- A Sources list. Issues carry a Sources section linking the references they drew on, so any claim can be checked at the primary source.
Engineering content
Design notes show the formula and the substitution, the way an engineer would, so the math is checkable rather than asserted. Where board-level shielding only treats a symptom, we say so and point at the underlying fix.
Corrections
