中龙集团 Dragon Group China Limited BIRD® A. BGA Rework Station 1. Knowledge about BGA BGA is short for Ball Grid Array. It is a kind of package method which use organic carrier in IC. It has the following features: ① Small package area.
Page 4 中龙集团 Dragon Group China Limited BIRD® (5)Good electrical property. The pins are small, the selfinductance and mutualinductance of the conductivity is low, and the frequency characteristic is good. (6)The tension between solder points produces good self-centration effect in solder-reflow, allowing 5% error of patch precision.
Page 5 中龙集团 Dragon Group China Limited BIRD® 3. Inspection standards of BGA For BGA assembled on PCB, inspection standard is a very important issue. Before BGA is applied to the PCB, most BGA manufacturers don't use X-ray in process of inspection. Instead, they employ some traditional methods to test PCB, such as automatic optical inspection, man-eye inspection or on-line function test.
Page 6 中龙集团 Dragon Group China Limited BIRD® No desoldering spots. (3)Bridging and short-circuit. When there is extra solder or the solder is not put on the right place, bridging and short-circuit may happen. So no bridging or short-circuit. (4)None paraposition. The X-ray image will show very clearly whether the BGA solder ball is aimed at the welding pad on PCB.
Page 7: Installation
中龙集团 Dragon Group China Limited BIRD® (1) Mounting: The main purpose of mounting to make every BGA solder align to the PCB pad with special equipment. (2)Hot air reflow: Hot air reflow soldering is the key to the whole BGA Rework.

After 1.5 periods of vibration, the PID self-setting is completed. Then the AT lamp is off. The meter can calculate the best PID parameter and save it in the meter according to the vibration period and amplitude.

For traditional PID meters, the identification of these parameters mentioned above is operated by experienced process control experts. Otherwise, it's likely that the entire system is out of control for the mismatch of the parameters which bring trouble to most users.

Page 28 中龙集团 Dragon Group China Limited BIRD® ceramic heater can't cool down very quickly, thus it is difficult to control the time of higher reflow temperature. However, the convection can control strictly, and it is conductive to a better & repeatable temperature curve, and the components will not be over-heated, and the time of higher reflow temperature will not prolong too much.

When the heat radiation distribute evenly, objects in different colors absorb and reflect heat radiation unevenly. The purchase decision of Array Package Rework Station should start from the reliable technology.
Page 30 中龙集团 Dragon Group China Limited BIRD® Generally, before mounting a new BGA, the paste should be laid on the pad with a special micro mesh. But for those common devices such as PBGA or MBGA, the paste can be laid on the pad directly, and the soldering can be finished by the melting of soldering balls.
