一、冷熱沖擊試驗(yàn)箱的用途有哪些？
冷熱沖擊試驗(yàn)箱適用電子元器件的**性能測(cè)試提供可靠性試驗(yàn)、產(chǎn)品篩選試驗(yàn)等，同時(shí)通過(guò)此設(shè)備試驗(yàn)，可提高產(chǎn)品的可靠性和進(jìn)行產(chǎn)品的質(zhì)量控制。
二、如何選購(gòu)冷熱沖擊試驗(yàn)箱？
1、沖擊溫度：沖擊溫度是指測(cè)試區(qū)實(shí)際能夠升、降到的溫度*大范圍。注意不是預(yù)熱和預(yù)冷室的極限溫度。
2、試驗(yàn)負(fù)載：這個(gè)參數(shù)直接影響能夠放置多少測(cè)試品。
3、恢復(fù)時(shí)間：指測(cè)試工件從一個(gè)溫度點(diǎn)切換到另外一個(gè)溫度點(diǎn)所耗費(fèi)的時(shí)間。常見的標(biāo)準(zhǔn)規(guī)定≤5min。
4、除霜時(shí)間：除霜間隔時(shí)間越長(zhǎng)越好?，F(xiàn)在有些廠家能夠做到1000cycles除霜一次，是非常理想的。除霜間隔越短說(shuō)明該設(shè)備的氣密性越差！
5、選擇三槽式或兩槽式，常規(guī)為三槽式。
三、購(gòu)置冷熱沖擊試驗(yàn)箱，售后服務(wù)如何？
1、東莞市貝爾試驗(yàn)設(shè)備有限公司為貝爾實(shí)業(yè)（香港）有限公司旗下公司，專業(yè)生產(chǎn)銷售的冷熱沖擊試驗(yàn)箱，嚴(yán)格按照訂貨日期送貨上門，并派技術(shù)人員現(xiàn)場(chǎng)免費(fèi)安裝調(diào)試，免費(fèi)培訓(xùn)操作員至到操作員會(huì)獨(dú)立操作為止。
2、我司生產(chǎn)銷售的冷熱沖擊試驗(yàn)箱，一律做到免費(fèi)保修壹年(自安裝驗(yàn)收之日起計(jì))，終身提供備件和售后服務(wù)48小時(shí)到位。。
3、在設(shè)備質(zhì)保期過(guò)后，如冷熱沖擊試驗(yàn)箱出現(xiàn)任何故障，通告我司之后，技術(shù)人員將****，并只收取工本費(fèi)用。 The matters needing attention for choose and buy High & low temperature shock test chamber
一、What the use of High & low temperature shock test chamber
High & low temperature shock test chamber of electronic components applicable safety tests provide reliability test, products such as screening tests, but at the same time, through this equipment test, can improve the reliability of the product and the product quality control.
二、How to choose and buy High & low temperature shock test chamber
1. Shock temperature: impact temperature is refers to the actual test area to rise, to the temperature of the maximum range. Note that not preheating and the cold room temperature extremes
2. Test load: the parameters directly affect how much can place test product
3. The recovery time: refers to test the work-piece from a temperature points switch to another temperature points the amount of time. Common standards ≤5min
4.Defrosting time: defrosting time interval between the longer, the better. Now some manufacturers can do 1000 cycles defrosting time, is very ideal. Defrost the shorter intervals that the equipment is the worse the air tightness
5.Choose three groove or two groove, routine for three groove
三、Purchase cold and hot shock test box, after-sales service
1.FollowingDongGuan Bell experiment equipment Co, Ltd Is its company,Professional production and sales of High & low temperature shock test chamber,strict according to order date door-to-door delivery, and send persons site free installation debugging, free training the operator to operators may be independent operation to so far.
2.Our company the production and sale of High & low temperature shock test chamber, all do one year warranty (since the installation acceptance date), a lifetime supply spare parts and after-sales service in 48 hours
3.After the warranty in equipment, such as c High & low temperature shock test chamber any fault, notice we later, technical personnel will door to door service, and charge only costs costs
