Partial HDI: A Complete Solution

10/10/2024 | I-Connect007 Editorial Team
We recently spoke with IPC instructor Kris Moyer about partial HDI, a process that’s recently been growing in popularity. Partial HDI allows designers to escape route out from tight-pitch BGAs on one layer, where a mechanically drilled plated through-hole is not an option, while avoiding the complexity and expense of sequential lamination cycles. As Kris explains, this process doesn’t add much to the cost, and it’s fairly straightforward. But there are some competing signal integrity and fabrication requirements to contend with. We asked Kris to walk us through this process.

Connect the Dots: Designing for Reality—Lamination and Materials

06/19/2024 | Matt Stevenson -- Column: Connect the Dots
As many of you have likely figured out, I am quite passionate about the subject of designing PCBs for the reality of manufacturing. I wrote a book about it and I participate in an I-Connect007 On the Line with… podcast series dedicated to the subject. This companion article will focus on multilayer lamination, keeping the bigger picture in mind: Realistic PCB designs should prioritize manufacturability and reliability of the PCB as well as meet the other design requirements. So, one must account for the production variables associated with individual manufacturing partners.

High Temperature Component Warpage as a Function of Moisture Sensitivity (MSL) Rating

05/29/2024 | Neil Hubble, Akrometrix
Moisture sensitivity requirements for non-hermetic surface mount devices are defined in the joint IPC/JEDEC standard J-STD-020E, “Joint IPC/JEDEC Standard for Moisture/Reflow Sensitivity Classification for Non-hermetic Surface-Mount Devices,” last updated in December 2014. This standard allows customers and suppliers to place electronics devices into specific categories, defined into 8 different moisture sensitivity levels (MSL). Test method criteria are defined within this standard to define MSL levels for different packages. A subsection of MSLs are shown in Figure 1 below, showing the MSL 3 and 4 used in this study.
