|Coreless Substrate Assembly & Reliability|
|Keywords: coreless, flip chip, advanced substrate|
|As the silicon nodes have moved to lower switching voltages the ability to maintain a clean and ample supply of current for the power planes is driving thinner cores and finer pitch substrates. The advanced build up substrates are already using 0.4mm thick cores and will be migrating to a coreless structure over the next couple of years. The reliability and assembly of these coreless substrates is quite challenging. This paper will briefly discuss the electrical drivers of coreless technology and will focus on the challenges and success of coreless substrate technology assembly and reliability.|
