Pyramax 125 低耗氮组件 • Process gas extract ed from zones 3 and 10 • Through flux management to first cooli ng zone • Returned back int o heated zones 1, 7 and 8
数字静压 – 结论
• As temperatures increase static pressures
decrease 数字静压随温度升高而降低
• Low static pressure 数字静压低
– Decreases peak temperature and dwell times
降低峰温和熔锡时间
– Increases peak delta T across products
增加产品上的温度偏差
• High static pressure 数字静压高
– Increases peak temperature and dwell times
增加峰温和熔锡时间 – 低的设定温度
– Improves heat transfer and thermal uniformity
改进热传输和热均衡性 – 无铅工艺窗口小
– Improves potential for one universal profile
改善工艺曲线

consumption reduction
• Customer payback less than 2 months!
– 1250 CFH down to 750 CFH, 500 CFH per hour
– 12,000 CFH per day savings (at $.01 / ft3)
= $ 120 / day
= $ 840 / week
= $3,360 / month
• Over $40,000 saving in one year!
