LEDWorker Lighting

How Does Shenzhen LED Worker Co., Ltd Guarantee the Quality?

• We have undergone CE, LVD, EMC, FCC, and UL certifications with a their-party company specializing in administrating these credentials. We continue to update our certifications terms any time new regulations and standards are introduced into the market to remain a top-tier manufacturer of LED strips that meet market demands.
• We reinvest in our advanced factory, and bespoke equipment that support our ability to produce more than 500,000 meters of COB LED light strips, and 300,000 meters of SMD LED strips per month. Our COB production line includes 34 die bonding machines, all equipment with related dispensers, board machines, reflow soldering, testing machines, and several custom ovens. Our SMD LED strip production line holds 2 Samsung placement machines, several reflow soldering options, and related modern equipment.
• At LED Worker, our design and development capabilities are incredibly strong. We pay special attention to product R&D of new products through the collaboration of our team members and joint leadership. A new product is released every three months on average that allows our production process to keep pace with the ever-changing marketplace. Our robust engineering capabilities allow us to provide customers with detailed OEM/ODM engineering design solutions.
• Over our 10 years of industry experience, we have developed processes that vastly improve our production systems, including:

1. Testing the VF value and direction of the LED light bead before producing the complete LED strip light. This avoids any faulty or unlit areas of the entire strip.
2. We pay close attention to the temperature of the solder paste to ensure a strong bond as well as watch the tail scraper after the stencil is applied, so the best amount of pastes is on 2/3 of the scraper. We have the experience to recognize that different PCB boards and brands of solder past require custom reflow temperatures. That is why we repeatedly test samples to confirm the combination of reflow, temperatures, and curve parameters are being met.

• We guarantee the production of raw materials. Our strict quality inspection standards allow us to meet the relevant laws or environmental standards of the countries we export into. We carefully screen out medium and long-term partners that can reliably provide quality raw materials for our LED strips. This includes manufacturers such as Hongqi. Their large production capacity and excellent reputation ensure our raw materials are perfect for our customer needs. The main cooperation PCBs supplied are pure copper wires above 2oz. That is why we also partner with LED manufacturers like Nichia and Samsung to ensure we always shave inventory on hand for client demands.
• We are proud to offer safe shipping with firm packaging methods, including:

1. Product box size of 11 x 106 x 24cm. The weight of the box will depend on different products. For example, a box of IP20 weights about 8kg and a box of IP65/IP67 about 11kg.
2. We are able to help with product transportation due to our extensive industry experience. We pack all our light strips in anti-static bags into thickened cartons that are sealed with transparent glue. We can add a side strip to reinforce the carton in the cases of longer or wider orders.

• LED Worker has extended value preservation periods. That is why we offer a product warranty that can be confirmed by pictures or videos after delivery. If the problem is on our end, we will pay the client in full. The warranty period varies between 3-5 years.

• We employ a strict quality control system to ensure all production standards are being met. This marries our sound production department sales team, QC, and other service processes like:

• Business Order Confirmation Process

1. Understand the product specifications and requirements the client needs.
2. Conforms whether the company’s production technology, product quality, price, delivery time, and any other needs are being met.
3. Confirm business order and complete release of requirements to PMC (Production and Material Control Department).

• PMC Order Process

• 1. This confirms and reviews the business order, after which the content of the remarks will be printed and released to ensure everything has been completed correctly. Special materials will be marked on the work order to remind the team of subsequent operational needs.
  2. The Process of Sending and Receiving Raw Materials
  3. Confirmation of the color temperature of the lamp beads (conform the batch and PINs to be used).
  4. Order confirmation and signature by warehouse staff (number of lamp beads, circuit board specifications, etc.).
  5. Review of lamp bead arrangement (color temperature of lamp bead used for engineering or quality confirmation).
  6. Confirmation and signature of the receiving personnel (number of lamp beads, specifications of circuit boards, etc.).

• Production Process of Glue-Dipping and Glue-Filling Products (including light strips and hard light strips products)

• 1. Quality confirmation of semi-finished products (all kinds of semi-finished products must be aged at least 1H or tested with glue).
  2. Test before dispensing and pouring glue (to confirm whether there is poor electrical property or color difference).
  3. Aging or test confirmation after pouring glue (aging does not exceed 0.5H, confirm that the product performance is passed).

• Inventory of Finished Product Delivery Process

• 1. Receipt of finished products from the warehouse (look at the list to find the products that meet the requirements).
  2. Confirmation of quality QC (testing or aging of finished products).
  3. Quality judgment (delivery judgment based on aging results).
  4. Packing and shipping of light strips (see order work).

• Packaging or Logistics Delivery Requirements

• 1. Check out the various specifications and packaging requirements listed on the invoice.
  2. Confirmation of product quality before packaging (color and electrical properties).
  3. Timely feedback and handling of any unexpected problems.
  4. Product packaging and shipping.

• Processing Flow of Abnormal Production

• 1. In the event an abnormal report is issued by the unit that discovered the issue, we will immediately find out the cause and give a new handling opinion that can pass the order to the PMC for tracking.

• Processing Flow of Customer Expectations

• 1. In the event a client requests an abnormal description, along with the defective products via images or video, our quality department will analyze the cause and report in a timely manner. This will inform the decision-making of the business to answer the customer and follow up with any changes to the client.

• Return Processing

• 1. When filing in the return order, we ask clients to include the precise reason for the return, and the number of specifications noted. The PMC will process this return, confirm the quality of the bad specifications, and, provided these are consistent with the details of the return order, confirm the underlying cause and offer handling advice. The PMC will follow up with the client concerning replenishment or replacement.

• SMT Workshop Product Process

• 1. The production workshop collects the materials from the warehouse that meet the work order requirements.
  2. The LED lamp beads will complete the dehumidification process of no less than 4H/60 degrees according to the quality requirements.
  3. We will then conduct the SMD job review. That is, the operator needs to carefully check the specifications and process requirements of each material in the work order.
  4. Verify the order materials (whether the received materials are in line with the order, especially to verify the resistance and wiring).
  5. Start the first patch (start to post a small number of products for testing to confirm whether the patch and materials are correct).
  6. Confirmation and judgment of the first piece (the first piece that has been pasted needs to be confirmed by the head of the production department).
  7. Order batch production (operators use the related materials in strict accordance with the order requirements applying quality control standards).
  8. SMD quality monitoring (pass furnace personnel need to do a good job controlling resistor materials and SMD).

LED Worker Work Cases and Customers

We are proud to have many large and well-known local and international clients, including Ford, Best Buy, Volvo, major grocery chains, and large retailers. The following information is a detailed description of a client engineering case:

In October 2017, an Australian customer came to China to visit the factory. Prior to his arrival, he has contacted more than 20 other suppliers and visited each over the course of 7 days. During these visits, our advanced engineering team was engaged in communication with him the entire time. It was because of this transparent and solid communication that the client felt a level of trust with our engineering team. After we confirmed his needs, he chose our company as his supplier. This was to make a beautiful Night Club project with a DMX control system combined with LED strip lights.

During these conversations, we found several technical difficulties to overcome, including:

• The complete DMS control system needed to work with LED strip lights and matching downlights.
• The final product needed different lengths and custom-made male and female connectors convenient for installation.
• The different connection methods of the main control and the sub-control required a targeted connection diagram to facilitate the construction by workers.
• Configure the most suitable power of the main controller and the sub-controller for the customer due to the power loss caused by the length of the cable.

We proposed the following solutions:

• Open the board to design the DMX512 downlight that matches the LED strip light for the customer.
• Make the length of the LED strip light to the customer’s requirements using bespoke male and female connectors of different lengths.
• As shown below, make a schematic diagram of the connection between the main control and the sub-control.
• Because of the installation problem, the line is relatively long in some places. We were able to leverage the skill and experience of our engineers to calculate the most suitable connection method between the main control and the sub-control for the customer.
