FAQ

1. How to understand Stock for Sale.

Answer:According to the company regulation, each standard product must be kept the stock of 1000pcs.

When the stock is less than 1000 pcs, we will put it into production at once instead of waiting for the orders. When the stock are more than 5000 pcs, the production must be stopped.

Appropriate stock is a very good support for the customer’s sampling and trial production demand.

The appropriate stock is also a guarantee of the quality. The production of the stock is always having more time than the production of the order. We have enough time to do more checking and to consider all the possible factors affecting the quality,
what’s more, in case that our products has been found a problem at the customer’s production, we have the stocked ones to do the replacement.

The appropriate stock is also a good way to reduce the cost. In busy seasons, we can produce the orders, while in free seasons, we can produce the stock. By this way, the labor source is maximumly used. At the same time, in free season, the materials can be bought at lower price.

2. How does Adia do for Never End of Supply?

Answer:EOL(End of Life) is largely because of end of life of the raw materials

When the EOL of the raw materials such as drivers and LCD panels happens, we can place a very large order with the supplier which may cover the consumption of one or two year. This large order is enough for the supplier to restart the production.

On the other hand, we can develop the replacement product which is mechanically and functionally the same as the previous one. For
the customer, only software will be changed a little while the hardware will remain the same.
 

Adia has built comprehensive relationships with the supplier samsun as LG, Hannstar and BOE and we can get the EOL products through our special channel to guarantee the continuous supply.

In LCD industry, due to the quick update of the technology, never end of supply is hard, but so far, Adia has never disappointed any customer.

Once the customer chooses us, we will offer the unchanged service till the end. Long-time relationship and mutual trust are our target and we hate well beginning but bad ending.

3. How to understand No MOQ?

Answer:The quantity of the order is decided by the market. As a supplier, we have no right to request the order must be more than any quantity. We have no MOQ request, a single piece is also a good order for us.

In another way, our products are always having stock, we don’t need to start the production for a small quantity, and we are capable enough of accepting the small orders.

However, if the quantity is small, the price will be higher.

4. How to understand in Full Range.
Answer:In full range means that our products are in great variety. We have what other manufacturers have, and we have what they don’t have. The customer is easy to find what they want in our product group. Like Walmart instead of Seven Eleven, all kinds of the products are placed before us and it is easy to attract the customers to come, so we like going shopping in Walmart, but we don’t like to go to Seven Eleven.

 

5. How does Adia guarantee the quality?

Answer: Adia has passed ISO9001:2008 certification. ISO principle is carried out in daily activities. The quality is strictly controlled in designing, material incoming, production process, equipment, management and checking and the rejects are not allowed to flow at any circumstances.

Adia has thousands of customers, in many cases, one product is being used by many customers. If one product is used by many factories, the quality is believable because most of the problems were solved already.

The Adia is following the quality standards from automotive industry. Special attention is paid to the capacity of anti-high-temperature, anti-shock and aftersales reliability. We don’t fear the rejects on the production line, we badly fear the rejects at the final consumer’s hand. Solving such kind of rejects are most costly. Adia is always pursuing 0 aftersales reject, so we adopted the strictest quality standards.

6. Why are Adia’s products higher in price?

Answer: The LCD quality has three standards: 1.consuming standards.2.Industrial standards 3.Automotive standards. Automotive standards are the highest grade which require the strong anti-shock capacity, anti-high-temperature capacity, high reliability and very low rate of reject. To follow automotive standards, we have to select the best raw materials, and bring in the most expensive equipment and very tough management, so our cost is higher.

In fact, our higher price is only manifested in samples. If the quantity is higher or the cooperation time is long, as long as the customer files the price request, the favorable price can be available after negotiation.

7. How long can we expect the samples?

Answer: Immediately in most of the cases.
