    Abstract: A solar cell module comprises a solar cell die that is soldered to a substrate. The substrate comprises one or more power contacts. A power conductor is soldered to a power contact, thereby electrically coupling the power conductor to the solar cell die. A pre-heat module heats a first side of the substrate at a first area to a first temperature for a first duration. Then, a solder heat source solders a power conductor to a power contact at a second area of the substrate at a second temperature for a second duration. The resulting solder connection at the power conductor is less prone to cold-solder defects. The temperature of the pre-heat module is controlled to promote curing of an RTV sealant used in the manufacture of the solar cell module. The temperature of the solder heat source is controlled to avoid burning and degrading of the RTV sealant.

    Abstract translation: 太阳能电池模块包括焊接到基板的太阳能电池模具。 衬底包括一个或多个电源触点。 电力导体焊接到电源触点，从而将电力导体电耦合到太阳能电池模具。 预热模块将第一区域的衬底的第一侧加热至第一温度持续第一时间。 然后，焊接热源在第二温度下将功率导体焊接到衬底的第二区域处的功率接触持续第二持续时间。 在电源导体处产生的焊接连接不太容易发生冷焊缺陷。 控制预热模块的温度以促进用于制造太阳能电池模块的RTV密封剂的固化。 控制焊料热源的温度以避免RTV密封胶的燃烧和降解。

    Abstract: A process for dressing a solder pad removes excess solder from locations that should be free of solder, such as circuit traces, other solder pads, and components near the solder pad being dressed. A first area of a substrate comprises solder to be removed and is heated to a first temperature. A second area of the substrate is heated to a second temperature. A vacuum nozzle is heated to a third temperature sufficient to melt the solder and is scanned across the area to be dressed, melting and vacuuming away the excess solder. The scanning process is controlled using a computer numerical controlled (CNC) machine.

    Abstract: An energy-efficient ventilation system comprises a ventilation fan, ductwork, system controller, and a plurality of ventilation points, each comprising a damper, a differential pressure sensor, a ventilation point controller, and a fume detector. When a ventilation point does not require ventilation, a signal is sent to the system controller to reduce the ventilation fan speed thereby using only as much energy as is needed to provide service to the ventilation points that need ventilation. The fume detector, damper, and differential pressure sensor for each ventilation point are used to determine whether ventilation is needed at a ventilation point and to control the ventilation point accordingly.
