1.目前，使用钢网涂覆散热硅脂的方法应用到AT9012项目上遇到一些难以解决的问题。最棘手的是涂胶后PCB板会贴附到钢网背面，灯板锁紧到后盖散热器后，焊接很不方便。
At present I have met some problems difficult to solve in applying the stencil method to the AT9012 project.The most intractable issues are:after printing thermal grease the PCBA board will be stuck to the stencil,another issue is when the LED board screwed sown to the back heatsink, it is not conveinent to solder the cable to the pads, because the space is too small.
2.散热胶并不是越多越好，我们只要做到保证PCB板与散热器良好接触就好了,过多的散热胶反而会使散热效果降低，进而影响流明值。
The thermal grease is not the more,the better,we just need to make sure the PCB board is completely attached to the heatsink.On the contrary,too much grease will reduce the heat transfer effect,and then affect the lumen output
3.用来学习的时间大多集中在晚上9点到11点
Time for learning are mostly concentrated at 9 to 11 o'clock in the evening
4.造成接线端子烧黑的原因是该点的探针没有下降到要求的位置，导致探针与接线端子没有良好接触，接触电阻过大导致局部电流过大产生火花，烧坏了器件
The reason of the terminal block burn and turns to black is the probe is not down to the right height,lead to the pin is not completely touch the terminal screw,the contact resistance becomes higher,hinder the current and then the contact point becomes very very hot, burn the terminal element.
5.今天开始使用心得散热硅脂，相比于以前的散热胶，新胶看上去更粘稠，我想着更适合于用钢网的方法涂覆
Today we start using the new thermal grease,compare with the old one,new grease looks more sticky,this will make it easier to apply the stencil method to the AT9012 project I think.
