From Blank Card to Rechargeable LCD Greeting Card: Our 8-Step Production Process

Have you ever wondered how a rechargeable LCD greeting card goes from a flat sheet of paper and a bare PCB to a finished product that plays video when opened? At Rophone, every rechargeable LCD greeting card passes through 8 carefully controlled production steps in our 5,000 square meter factory in Dongguan, China. In this article, we walk you through our complete rechargeable LCD greeting card production process, from raw material inspection to final shipping.

1. Step 1: Raw Material Inspection

The first step in making a rechargeable LCD greeting card is inspecting every incoming raw material. Our QC team checks every batch of 1200g rigid greyboard, 157g coated art paper, LCD screens, lithium batteries, PCBs, speakers and USB ports before they enter the production line. We measure paper thickness, test battery voltage, verify screen brightness and run a 10-minute video playback test on every batch of PCBs. Any material that fails our inspection is returned to the supplier. This ensures that only the best materials go into every rechargeable LCD greeting card we produce.

2. Step 2: Printing and Finishing

Once materials pass inspection, the cover paper for the rechargeable LCD greeting card goes to our in-house printing department. We use Heidelberg offset presses for accurate Pantone color matching. After printing, the cover paper is laminated with matte or glossy film, then foil-stamped, embossed or spot UV coated as specified. Each printed sheet is inspected for color consistency, registration accuracy and print quality before it moves to the die-cutting stage. The cover of a rechargeable LCD greeting card is the first thing the recipient sees, so print quality must be perfect.

3. Step 3: Die-Cutting and Paper Folding

The printed and laminated cover paper is precision die-cut to the exact rechargeable LCD greeting card shape. Our die-cutting machines use sharp steel rules that cut clean edges without tearing the paper. The greyboard is also die-cut to size. Skilled workers then fold and glue the cover paper onto the rigid greyboard, tucking the edges neatly by hand. This hand-folding process is what gives a rechargeable LCD greeting card its premium, seamless finish. Machine-glued boxes never look as clean as hand-folded ones.

4. Step 4: PCB Assembly and Video Loading

In our dust-free electronics workshop, technicians solder the LCD screen, lithium battery, speaker, USB port and sensor switch onto the custom PCB for each rechargeable LCD greeting card. Every PCB is then programmed with your video content using our proprietary video encoding equipment. The video is tested for playback quality, audio sync and screen brightness. This is the most critical stage of rechargeable LCD greeting card production, and it is done by experienced technicians who have been with Rophone for 5+ years.

5. Step 5: Final Assembly

The tested electronic module is precisely recessed into the die-cut greyboard of the rechargeable LCD greeting card. The screen sits flush with the card surface, and the USB port is aligned with the cutout on the edge. The sensor switch is positioned so that opening the card triggers playback instantly. A team of 20 assembly workers handles this stage, each rechargeable LCD greeting card taking about 3 minutes to assemble by hand. We do not use automated assembly machines because they cannot achieve the same precision and finish for a rechargeable LCD greeting card.

6. Step 6: Quality Control and Burn-In

Every rechargeable LCD greeting card goes through our QC lab before packaging. We test playback time, battery charging, screen brightness, audio volume, sensor sensitivity and cover finishing. We also run a 72-hour burn-in test on a random sample from each batch. During burn-in, the rechargeable LCD greeting card plays video continuously to detect any early failures. Only when the entire batch passes does the rechargeable LCD greeting card get approved for packaging. You can learn more about our rechargeable lcd greeting card quality standards on our product page.

7. Step 7: Packaging and Cartoning

Approved rechargeable LCD greeting card units are individually packed in clear poly bags to protect the cover from scratches. They are then packed into 5-layer export cartons. Each carton contains a specific quantity based on the rechargeable LCD greeting card size. We work with experienced freight forwarders who specialize in shipping lithium battery products internationally. Every carton includes the UN38.3 battery safety report for customs clearance.

8. Step 8: Shipping and After-Sales Support

Once the rechargeable LCD greeting card order ships, Rophone provides full after-sales support. We track every shipment and provide tracking numbers as soon as the goods leave our factory. If any rechargeable LCD greeting card arrives defective, we replace it free of charge. Our production time is 7 to 10 working days after artwork approval, with sample orders taking 3 to 5 days.
