Inside Our Rechargeable LCD Greeting Card Factory: Production Line and QC Process

Have you ever wondered how a rechargeable LCD greeting card is made? At Rophone, we have been manufacturing rechargeable LCD greeting card products for over 10 years in our 5,000 square meter factory in Dongguan, China. In this article, we take you inside our production line and show you exactly how every rechargeable LCD greeting card goes from raw material to finished product before it ships to brands around the world.

1. Inside the Rophone Rechargeable LCD Greeting Card Factory

Our factory specializes exclusively in rechargeable LCD greeting card production. We have 8 production lines, 120 skilled workers and a monthly capacity of 200,000 units. Every rechargeable LCD greeting card we produce passes through 12 production stages and 3 quality control checkpoints. Unlike general packaging factories that also make boxes and bags, Rophone is focused 100 percent on rechargeable LCD greeting card and electronic greeting card technology.

When you visit our factory, the first thing you notice is the clean, organized production floor. Each rechargeable LCD greeting card production line is separated into stations: die-cutting, screen assembly, PCB testing, paper wrapping, final assembly and packaging. No rechargeable LCD greeting card moves to the next station until it passes inspection at the current one. This strict workflow is why our defect rate is below 0.5 percent.

2. Rechargeable LCD Greeting Card: Material Preparation Stage

Every rechargeable LCD greeting card starts with raw materials. We source 1200g rigid greyboard from certified FSC paper mills. The greyboard is precision die-cut to the exact card size. Simultaneously, the LCD screens, lithium batteries, PCBs and USB ports are inspected and tested before they enter the rechargeable LCD greeting card assembly line.

The cover paper for the rechargeable LCD greeting card is printed in our in-house printing department. We use Heidelberg offset presses for vibrant, accurate color matching to your brand Pantone colors. After printing, the cover paper is laminated with matte or glossy film, then foil-stamped and embossed as specified. Only after the cover passes visual inspection does it move to the next stage of rechargeable LCD greeting card production.

3. Rechargeable LCD Greeting Card: Screen and PCB Assembly

The most critical stage of rechargeable LCD greeting card production is screen and PCB assembly. Our technicians solder the LCD screen, battery, USB port and sensor switch onto the custom PCB. Each rechargeable LCD greeting card 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 before the rechargeable LCD greeting card moves on.

This stage is done in a dust-free workshop. Static electricity can damage the sensitive electronics inside a rechargeable LCD greeting card, so all technicians wear anti-static wrist straps and work on grounded tables. We test 100 percent of PCBs at this stage. Any rechargeable LCD greeting card with a screen defect, audio problem or battery issue is immediately pulled from the line and repaired. This ensures that only fully functional rechargeable LCD greeting card units move to final assembly.

4. Rechargeable LCD Greeting Card: Final Assembly and QC

In final assembly, the electronic module is precisely recessed into the die-cut greyboard. The cover paper is glued onto the rigid board. A team of skilled workers folds and tucks the paper edges by hand to create a clean, seamless finish. Each rechargeable LCD greeting card is then closed and opened 3 times to test the sensor switch and automatic playback.

After assembly, every rechargeable LCD greeting card goes through our QC lab. We test playback time, battery charging, screen brightness, audio quality and cover finishing. We also run a 72-hour burn-in test on a random sample from each batch. 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 production specs on our product page.

5. Rechargeable LCD Greeting Card: Packaging and Shipping

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 and weight. We work with experienced freight forwarders who specialize in shipping lithium battery products internationally. Every carton of rechargeable LCD greeting card includes the UN38.3 battery safety report for customs clearance.

Production time for a rechargeable LCD greeting card order is 7 to 10 working days after artwork approval. Sample orders take 3 to 5 days. Whether you need 50 pieces for a small event or 10,000 pieces for a global launch, our factory can scale production to meet your timeline.
