LNEYA represents the international advanced liquid temperature control technology, actively explores and studies component testing systems, mainly used for temperature test simulation in semiconductor testing, with wide temperature orientation and high temperature rise and fall, temperature range -92°C ~ 250°C, suitable for various Test Requirements. LNEYA is committed to solving the problem of temperature control lag in electronic components. Ultra high temperature cooling technology can be cooled directly from 300°C.
This product is suitable for precise temperature control of electronic components. In the manufacture of semiconductor electronic components for harsh environments, the IC packaging assembly and engineering and production testing phases include electronic thermal testing and other environmental testing simulations at temperatures (-45°C to +250°C). Once put into practical use, these semiconductor devices and electronic products can be exposed to extreme environmental conditions to meet demanding military and telecommunications reliability standards.

LNEYA attends various exhibitions at home and abroad every year. At the exhibition, we show the latest research equipment of LNEYA. Every year, long-term cooperative customers will come to exhibitions and communicate with us. We are also actively developing new customers to provide them with high quality machines and services.
After sale service
Guarantee that the goods are sold to be conform to the provisions of the contract and qualified new products by factory inspection, quality performance, technical indicators and configured are in accordance with manufactures and technical documents stipulated in the contract.
Installation and debugging
After the arrival of the goods, my company or my company agent is responsible for installation and debugging of equipment need on-site installation and debugging.
Inspection and acceptance
After installation and debugging, acceptance by the customer to confirm the goods to be conform to the provisions of the contract and qualified new products, quality performance, technical indicators and configured are in accordance with manufactures and technical documents stipulated in the contract, and after the confirmation of a full set of technical documents, sign the installation acceptance report and confirm acceptance.
At the same time of installation and debugging of equipment, my company’s after-sales service engineer is responsible for technical training for user until user can be skilled of operation. In the process of using equipment by customer, customer can consult relevant technical issues to after-sales service personal of our company at any time, according to the situation, my company will arrange training on site or remote.
After sale service commitment
A full free one year warranty since the date of acceptance, during the warranty period, all repairs and spare parts are free of charge(instrukent malfunction caused bu human factors will be charged of cost price of spare parts); After the warranty period, we will be responsible for maintenance of equipment for lifetime, according to the actual maintenance fees, appropriate fee will be charged.
(PS:There will have extra charge if the customer need on-site service. And customers need to describe the issue first and then send some failed pics or videos in advance, then Lneya judge if it is possible to go for after-Sales on site. )
