1. Advantech Industrial Computer: The leader in Taiwan’s industry, product performance is okay, but the price is on the high side and the price/performance ratio is not very good. Bidding and designation are mostly used. Direct sales mainly focus on large orders, and small orders are left to dealers. This way, the service is somewhat unstandardized, with many processes and slow speed. 2. EVOC Intelligent: A domestic brand, it is fighting a propaganda war, which is a bit inconsistent with its name. Judging from the usage, there is indeed a gap with Taiwan's products, but the price is relatively cheap. Just, the service is average. Although there are branches and dealers in various places, how can agent B be willing to provide services for agent A when agent A sells the machine? 3. Shuokong Intelligent: Domestic brand, 4U industrial computer SK-2410, integrated workstation SK-3848, tablet computer SK-P3715 and other models are relatively stable in terms of industry stability. After using it for 3 years, the technology and service are relatively good. It’s just that the brand has not yet emerged, and the price is mid-to-high. Currently, the automation industry has launched a series of measurement and control data acquisition cards, and the motion control card has relatively complete functions. If we consider stability and price, I think this combination is not bad. 4. Axiomtek Technology: Mainly focused on boards. The stability is good, I have used his small board before. The competition is huge and the current market occupancy rate is not very high. 5. North China: The price is super cheap. The stability is very poor, and the later services will be enough to give you a headache. Cheap ones are not necessarily bad, but if the manufacturer sells them with basically no profit, our factory would not dare to use them anyway, haha. The manufacturer has no profit, so what can he do to guarantee your later service? 6. SOKON: A rising brand in China, it mainly provides OEM-engraved products. It is unknown and integrates some advantages of various industrial computers. It has rich experience in customizing chassis and has many motherboard options. It does a good job. The model is mainly direct sales, and no profit is given to dealers, but direct pre-sales and after-sales tracking services are much faster. The price/performance ratio is pretty good and meets the requirements of Chinese people. 7. Siemens machines are said to be very stable. But the prices are above 10,000, so if you consider the cost, don’t use them. However, good stable performance can indeed reduce later maintenance costs. Overall, the price/performance ratio is still not suitable. 8. German Kontron, IEI, ADLINK, etc., like Siemens, have good performance and good quality, but in terms of price/performance, they are still a bit high. The above is a personal evaluation, focusing on recommended brands. Each brand has its own strengths. If the evaluation is inappropriate, please don't mind.
