Background - IT Market Disruption

• Our “Post PC Era” :• Sales of desktop & laptops declining

• Smartphones & tablets becoming dominant internet user devices

• Cloud Computing and SAAS eroding the packaged software model

• Ultrabooks, hybrids and “modular” PCs replacing traditional PCs

• Commodity servers rivaling OEM brand systems for internet enterprises

• “Internets of Things” = explosion of embedded system modules

Background – HDI/ALV Design

• Handheld/wearable electronic packaging:• Design envelope dominated by batteries & displays

• Miniaturized & modularized PCBA design with high flex content

• Extensive use of SoC & MEMs, with SiP, PoP & WCSP packaging

• Low profile CSP, WCSP & microQFN devices, 0.40~0.30mm pitch

• Ultra-thin 8-14 Layer HDI PCB design, current and near term:

• Via in Pad/stacked via ICT with decreasing pad diameter

• Conductor line/space design rules approaching 40/60um

• 2 track routing in 0.40umm pitch devices up to 36x36 BGA

• 25~40um dielectrics

• 250~800um thickness

• Flex & coreless HDI

Project – Purpose & Objectives

Problem

• Test vehicles for BGA & HDI technology lag by a decade• Do not reflect current design practice & materials

• Falling into dis-use by practitioners in favor of EOL product testing

• Creating a void in up-stream device and materials development

Objective

• Create/validate an open source ALV-HDI test vehicle based on current & near term Smartphone design practice• General purpose test patterns for ALV PCB and assembly level tests

• Reference drop test vehicle for JESD-B22-111 (existing design)

• Smartphone forma factor for JESD-B22-111 validation (new design)

• Run validation tests for proof or concept/design & standardization

Project – Goals & Deliverables

Goals

• Build a collaborative working group handheld product technology within HDP for this and future projects

• Stakeholders from Materials, PCB, Packaging and Assembly

• Establish a suite of basic methods and tools suitable for the general assessment of the technology

• Build & test first generation TV designs for validation

• Deliverables:• Generic, modular, Test Vehicle form factor spec & DFM

guidelines

• General purpose test vehicle & drop test vehicle designs in Gerber

• Demonstrator samples for future reference

• Test data and reports for proof of concept build

Page 11: Ultra Thin HDI Multi-purpose Test Vehicle Definition Stage Project C.B. Katzko, TTM Technologies HDPUG Member Meeting, 2014 June 04 Düren, Germany Hosted.

Project – TV Design Goals

The TV form factor should have the capability to:

• Scale to smartphone or handheld device form factors, materials sets and production formats typical of the art

• Include as a design technology baseline:• Modularized, based on 50mm x 50mm increments for various

mixes of bare board & assembly TVs

• 0.40mm pitch BGA & 0.30mm pitch WCSP test devices

• 01005 chip passives (low value or zero ohm resistors)

• 40/60um nominal line/space design rules

• All Layer Via interconnect with stacked vias, Via in Pad

• 12 layer build-up in plane/signal pattern configuration and pattern density typical of the art for Smartphone logic boards

• PCB materials typical of the art with FR4.1 with 1037 & 1067 reinforcement incorporated in the design
