好質量的PC板是怎么差異的呢，不太熟悉PC作業的客戶就需要多了解一下。正本只需夠細心，就會輕松的遠離劣質的耐力板。在拿到PC板的時，首要需要看產品的包裝，看產品的保護膜貼的是不是無缺。外觀夠不夠規整，這也算是形象分，一個廠家不注重產品的包裝，不是說產品的質量也會有什么問題，但這方面總會給客戶留下一些欠好的形象。就象往常買東西一樣，包裝精巧的產品，我們老是更甘心去收購一樣。
How good quality PC board is difference, not familiar with PC operation will need to know more about the customers. The original just enough careful, can easily away from poor endurance plate. When get the PC board, first need to see the product packaging, see whether the protective film of product. Enough neat appearance, it is image points, and a factory does not pay attention to product packaging, not to say that the quality of the products have what problem, but will always leave some owe good image. Just like usual shopping, packaging exquisite products, we are always more willing to purchase.
1.看完包裝，再來看產品本身的質量。把產品的保護膜掀開，查詢PC板的外表，假定有很多氣泡和顆粒，那說清楚耐力板的材料一定不是用的最好的。一般國外進口的材料，也即是十年質保的PC板是很難看到顆粒和氣泡的。
1. The finish packing, look at the quality of the product itself. By the product's protective film, query the appearance of PC board, assuming there are a lot of bubbles and particles, the clear endurance plate must not use the best material. General imported materials, namely ten years warranty, PC board is difficult to see particles and bubbles.
2.其次，還要看看耐力板透明度高不高。還可以在陽光下暴曬一段時間，假定有些有發黃，透光不佳，甚至有霧化，那么這一定也是質量比較差的。還有一種比較簡單的查驗方法即是在PC板的下面放一張白紙，透過白紙看耐力板是不是發黃，發黃嚴重即是材料差的，不發黃的即是材料比較好的。
2. Second, seeing endurance high transparency is not high. Can also be a period of time in the sun insolates, assuming that some have yellow, pervious to light, and there are even atomization, then this must be poor quality. And a simple inspection method is put in the bottom of the PC board a blank sheet of paper look at endurance plate through the white paper is yellow, yellow serious material is bad, not yellow material is better.
3.假定有條件，還可以將拿很小的耐力板進行查驗，用打火機將它點著，質量較好PC源料出產的耐力板會在脫離火源的一段時間自己暫停，熔化后可以拉很長，因為PC板材料分子量較高，這種板材才不容易折斷和破碎。
3. Suppose there are conditions, can also take small endurance plate for inspection, burning it with lighter, better quality PC material, produce of endurance plate will be out of the fire of his suspended for a period of time, after melting, can pull a long, because the PC board material molecular weight is higher, the board is not easy to break and broken.
