(7)Compatible with original SMT mount technology and machines. The original screen printer machine, mounter and solder-reflow machine all can be used. The comparison between BGA and QFP is shown in Table 1.
- Page 5 point is that the welding spots can still be welded on the pad. The ideal situation is no poor welding. Poor welding may be caused by pollution or the uneven distribution of flux paste. What's more, warped PCB may also lead to poor welding. Open-circuit welding spot may exist, too.

Panel display When we turn on the meter, the upper screen displays the basic model, the lower shows the version of the software (for the customized meter, the customer should pay special attention to the software version, to facilitate future order). Three seconds after, the upper screen displays measurements (PV), the lower screen displays settings (SV).

I. Related information 1. How to deal with the Voids produced by the lead BGA in lead-free soldering? As the development of the lead-free technology, more and more SMT processing enterprises come across the problem of Voids in production. Many companies try to avoid using lead BGA in lead-free soldering technology. Because the melting point of lead soldering balls is lower than lead-free tin paste. - Page 28 analysis of material temperature. The convection rework station which can save many temperature curves is directed by the approximate situation of PCB heating. The more precise method is to connect a K sensor to the PCB to detect the temperature. What’s more, the final form of process control is to detect the welding points in the process, or to detect the reflow points.
- Page 29 The Full component is entirely covered by the beam, and BGA can be heated evenly. In the Case of the ZM-DGC 900, You can chose a diameter of the heat you want to apply according to the size of the IC Component you will work on.
