Q:How do I request a quote?
Kindly send us CAD/AI/CDR vector file or original sample for precisely quotation.
Q:Do you provide prototypes and what is the lead time?
We can provide prototypes with minimal cost to you. Delivery date of final-drawing takes 2 workdays, new samples take within 10 workdays, and mass production takes within 2 weeks.
Q:What is the best material for a graphic overlay and how is it printed?
PET/PC/Acrylic can be used depending on the application. For membrane switches, polyester is recommended for its chemical resistance and long cycle life. Graphics are applied via silkscreen or digital printing on the second surface to protect the image, typically using Pantone colors.
Q:What is the difference between silver flex and copper flex circuits?
Silver flex uses screen-printed conductive ink on polyester, suitable for applications under 1W at lower cost. Copper flex circuits handle higher current/voltage with lower resistance and support dense arrays, though at a higher cost.
Q:What are the circuit pitch constraints and connection options?
Copper flex circuits allow a minimum pitch of 0.5mm, whereas silver flex circuits allow a minimum pitch of 1.0mm.
Q:What methods are available for backlighting a membrane switch?
Common options include: A) LEDs, frequently used for keys, icons, and indicators; B) Light Guide Film (LGF), for uniform illumination with fewer LEDs; C) Electroluminescence (EL), providing an ultra-thin uniform lighting layer between the overlay and circuit.
