A radio-frequency (RF) shield pad is “dressed” by automatically removing melted solder from the shield pad by traversing a pattern of the shield pad. After an RF shield has been removed from a shield pad of a printed circuit board (PCB), the PCB is pre-heated to a temperature sufficient to heat solder on the shield pad and to prevent thermally stressing the PCB during the dressing process. The solder is melted, such as by a heated tip of a desoldering tool, and the melted solder is vacuumed while the tip automatically traverses the pattern of the shield pad, until all or a threshold amount of the melted solder has been removed from the shield pad. After the PCB has been reworked, solder paste is automatically disposed on the RF-shield pad, the RF shield is temporarily mounted on the RF-shield pad, and the PCB is processed in a reflow oven, thereby securely attaching the RF shield to the PCB.

Approach for generation of power failure warning signal to maximize useable hold-up time with AC/DC rectifiers
A method of optimally generating a power failure warning (PFW) signal has been disclosed here in such a manner that adjusts timing of PFW signal generation according to load conditions in case of input AC voltage loss. A PFW voltage threshold value can be set at a lower value under light load conditions and at a higher value under heavy load conditions. PFW signal generation can also be triggered by a timing mechanism that is set when a bus voltage drops to a voltage threshold value. A countdown time of the timing mechanism is set according to a determined bus voltage drop rate. In this manner, issuance of the PFW signal is delayed for lighter load conditions and the power supply unit is capable of extending normal operation under lighter load conditions before the PFW signal is issued.

The reconfigured digital PWM modules remain set in the independent operation mode for a predefined period of time. Once the predefined time period is reached, the reconfigured digital PWM modules are again reconfigured back to the original complementary operation mode configuration and the control algorithm resumes normal operation of the DSC and digital PWM modules.

The power regulation control circuit is implemented during two modes. A first mode is a sleep mode and a second mode is a wake-up mode. During the sleep mode, the power supply detects a no-load presence and artificially increases the output voltage Vout to its maximum allowable value. In some embodiments, this is accomplished by pulling up an output of a error amplifier that feeds a PWM module. During the wake-up mode when the power supply wakes up from the sleep mode under maximum load, the output voltage Vout sinks from the artificially higher voltage, but still stays above a minimum operational voltage level. A slew rate compensation can be implemented to control a rate at which the output voltage drops when a load is applied. The artificially high output voltage during no-load condition and the slew rate compensation provide open loop voltage adjustment.
