Patent number: 11963307Abstract: A ball-grid-array component of a ball-grid array assembly is analyzed prior to reflow. A predicted warping pattern of the ball-grid-array component that is likely to occur during reflow is predicted based on the analyzing. A solder ball ball-grid-array defect that could be caused by the predicted warping pattern is predicted. An initial via suction pattern to mitigate the ball-grid-array defect is assigned. A vacuum head is applied to a via in the ball-grid-array assembly. The solder ball is located at the opposite end of the via from the vacuum head. Suction is applied to the via based on the via suction pattern. The suction draws a portion of the solder ball into the via during reflow.Type: GrantFiled: March 30, 2021Date of Patent: April 16, 2024Assignee: International Business Machines CorporationInventors: Matthew Doyle, Thomas W. Liang, Layne A. Berge, John R. Dangler, Jason J. Bjorgaard, Kyle Schoneck, Matthew A. Walther

Patent number: 11948807Abstract: A set of features for a product is identified. It is determined that preventing an electrical connection at a ball-grid-array location on a ball-grid-array assembly of the product would result in the set of features. The ball-grid-array location is established as a target BGA location based on that determination. Suction is applied to a via at the target BGA location during reflow of the ball-grid-array assembly. With that application of suction, a solder ball at the target BGA location is drawn into the via.Type: GrantFiled: March 30, 2021Date of Patent: April 2, 2024Assignee: International Business Machines CorporationInventors: Matthew Doyle, Thomas W.

Publication number: 20240097292Abstract: A voltage source watchdog comprising a passive device is placed in series between a voltage source and a load. The passive device includes an electromigration (EM) joint of known materials that will create an electromigration void after a specified amount of current passes through the EM joint. After a known amount of current as passed through, a void is created and a voltage will no longer be sensed, thus providing a sure safety mode situation. When the voltage source is a battery, the battery life may be extended by selectively enabling voltage measurement operations for the proposed watchdog.Type: ApplicationFiled: September 16, 2022Publication date: March 21, 2024Inventors: Mark K. Hoffmeyer, Matthew Doyle, Kyle Schoneck, Layne A. Berge, Matthew A. Walther, Thomas W. Liang, John R. Dangler, Jason J. Bjorgaard
