We will save your important circuit board with a highly specialized and difficult modification.
In K-All's special modifications, we save our customers' important circuit boards through challenging and specialized modifications such as jumpers from the inner layers of the substrate and jumpers from LGA, achieving shorter delivery times and providing results that exceed simple circuit board remakes. Just like with regular pattern cuts and jumpers, we can also perform jumpers and pattern cuts for BGA and LGA. In most cases, this can be done at a lower cost and with a shorter lead time compared to circuit board revisions, so please don't hesitate to consult us. 【Features】 ○ Save important circuit boards with challenging special modifications ○ Achieve shorter delivery times ○ Provide results that exceed simple circuit board remakes For more details, please contact us or download the catalog.

basic information
【Case Studies】 [Want to cut and jumper the wiring of the intermediate layer] ○ Successfully cut the pattern of the intermediate layer on a build-up board and pulled jumper wires from the 4th layer of an 8-layer board to incorporate a filter. [Want to create an IC checker with PC⇔USB connection specifications] ○ Prepared an IC socket to enable the replacement of the memory controller (QFP). ○ Manufactured a socket mounting board for installation on a USB memory. ○ Removed the memory controller and connected all pin jumper wires between its footprint and the board. ○ Fixed the board with the USB memory and socket using a jig (the jig was also designed by K-All). [Since I made a mistake with the BGA pattern pin by pin, I want to wire jumpers from all pins of the BGA] ○ During operation verification, a wiring mistake in the BGA pattern was discovered, as all pins were misaligned by one pin. Since this was for prototyping, jumpers were made from all pins of the BGA, and operation verification was cleared. *Currently, for such jumpers, using a conversion board with POP is a more reliable solution. ● For more details, please contact us or download the catalog.

Applications/Examples of results
■Circuit modifications around the substrate and BGA are necessary. "We need to modify the circuits around the substrate and BGA, but we don't have time to revise the substrate." "I want to swap patterns for testing, but I want to keep costs down." Please consult or contact K-All. With over 25 years of know-how, we can assist with BGA jumpers and more.

Company information
Our company was founded in 1990 with four members. At the time of our establishment, we had no equipment, and each of us primarily worked on renovation projects and manual assembly with just a soldering iron. As the miniaturization of components progressed and the number of prototype and development projects involving BGA increased, so did the demand for BGA reballing and jumper wiring. Therefore, we introduced BGA rework equipment before implementing basic devices such as reflow ovens. Since then, we have conducted extensive research in technology alongside numerous customers, and we take pride in having established a level of reliability that satisfies our clients, not only for BGA but also for LGA, POP, underfill applications, and 0402 chip mounting. Other features of our company include the establishment of a RoHS-compliant factory, maintaining a constant inventory, and providing mounting support for cut parts (My Data), which differentiates us from other companies in the same industry. It is our mission to respond to all QCD (Quality, Cost, Delivery) requirements necessary for development and prototype assembly, and we are committed to providing technical support with customer satisfaction as our top priority.
