Grounding, shielding and absorption solve different electromagnetic paths.
01Conductive adhesive films, fabrics and metal foils create electrical paths that can bridge seams, ground components and reduce coupling when the enclosure and contact design are correct. The adhesive alone cannot guarantee system-level shielding.
02Absorbers use magnetic and dielectric loss in a polymer composite to attenuate electromagnetic energy over a grade-specific frequency range. Placement, thickness, field orientation and proximity to antennas or wireless-power coils can change the result.
03Resistance must be reported with direction, contact load, geometry and fixture. Shielding or absorption claims must state frequency and assembled test conditions; a generic high-performance statement is not technically meaningful.

أسئلة المهندسين قبل تجربة خط الإنتاج.
حدّد وظيفة المادة والأسطح البينية ونافذة العملية قبل طلب العينة.
Is an EMI absorber the same as a conductive shield?+
No. A conductive shield redirects or contains current and fields through a conductive structure; an absorber dissipates part of the electromagnetic energy through material loss. Some assemblies use both.
How are ECLEAR EMI grades selected?+
Selection starts with the shielding or absorption target, frequency range, available thickness, grounding path, assembly pressure and reliability profile. Named ECLEAR grades are then compared using the current controlled TDS and a representative device-level test.
Can ECLEAR recommend a grade from an application description alone?+
A first shortlist is possible, but a production recommendation requires the substrate, layer construction, equipment, process sequence, test method and acceptance criteria. ECLEAR normally moves from requirement definition to laboratory matching, samples, line trial and a frozen approved specification.
Are the values shown on this page guaranteed specifications?+
No. Website values and constructions are selection guidance. Guaranteed limits, test conditions, packaging and shelf life are controlled only by the latest ECLEAR-approved TDS, quality agreement and customer qualification record.
