Effect of Thermal via Design on Heat Dissipation of High-Lead QFN Packages Mounted on PCB

Jul 24, 2024 | Ziyi Yuan, Dongyan Ding and Wenlong Zhang

The quad flat no-lead package (QFN) is widely used in integrated circuits due to its
advantages in performance and cost. With the increasing power of electronic products, effective
heat dissipation from QFN packages has become crucial to prevent product damage. The focus of
this study is to investigate the thermal performance of QFN packages soldered onto printed circuit
boards (PCB) by finite element analysis (FEA). Conventional QFN, dual-row QFN, and high-lead
QFN packages were modeled and compared by ANSYSY software. The effect of thermal via design
(the distance, number, distribution, diameter, and thickness of thermal vias) on the QFN package
was investigated. The study revealed that the high-lead QFN package consistently demonstrated
superior heat dissipation performance than the other two under different conditions. Placing thermal
vias closer to the heat source enhances heat dissipation efficiency. Thermal vias positioned beneath
the thermal pad were particularly effective. Increasing thermal via quantity and diameter improved
heat dissipation, with square distribution layouts showing advantages. However, excessive copper
plating thickness can increase thermal resistance and hinder heat dissipation.

THE IMPACT OF VIA AND PAD DESIGN ON QFN ASSEMBLY

Jul 24, 2024 | Jennifer Nguyen, David Geiger and Anwar Mohammed

Quad Flat No-Lead (QFN) packages has become very popular in the industry and are widely used in many products. These packages have different size and pin counts, but they have a common feature: thermal pad at the bottom of device. The thermal pad of the leadless QFN provides efficient heat dissipation from the component to PCB. In many cases, arrays of the thermal via under the component is used to dissipate heat from the device. However, thermal vias can create more voids or result in solder protrusion onto the secondary side....

Pad Design and Process for Voiding Control at QFN Assembly

Jul 24, 2024 | Derrick Herron, Dr. Yan Liu, and Dr. Ning-Cheng Lee

Quad Flat No Leads (QFN) package designs receive more and more attention in electronic industry recently. This package offers a number of benefits including (1) small size, such as a near die size footprint, thin profile, and light weight; (2) easy PCB trace routing due to the use of perimeter I/O pads; (3) reduced lead inductance; and (4) good thermal and electrical performance due to the adoption of exposed copper die-pad technology. These features make the QFN an ideal choice for many new applications where size, weight, electrical, and thermal properties are important. However, adoption of QFN often runs into voiding issue at SMT assembly. Upon reflow, outgassing of solder paste flux at the large thermal pad has difficulty escaping and inevitably results in voiding. It is well known that the presence of voids will affect the mechanical properties of joints and deteriorate the strength, ductility, creep, and fatigue life. In addition, voids could also produce spot overheating, lessening the reliability of the joints....

Heat Sink Induced Thermomechanical Joint Strain in QFN Devices

Jul 24, 2024 | Gerard McVicker, Vijay Khanna, and Sri M. Sri-Jayantha

A blade server system (BSS) utilizes voltage regulator modules (VRMs), in the form of quad flat no-lead (QFN) devices, to provide power distribution to various components on the system board. Depending on the power requirements of the circuit, these VRMs can be mounted as single devices or banked together. In addition, the power density of the VRM can be high enough to warrant heat dissipation through the use of a heat sink. Typically, at field conditions (FCs), the BSS are powered on and off up to four times per day, with their ambient temperature cycling between 258C and 808C. This cyclical temperature gradient drives inelastic strain in the solder joints due to the coefficient of thermal expansion (CTE) mismatch between the QFN and the circuit card. In addition, the heat sink, coupled with the QFN and the circuit card, can induce additional inelastic solder joint strain, resulting in early solder joint fatigue failure. To understand the effect of the heat sink mounting, a FEM (finite element model of four QFNs mounted to a BSS circuit card was developed. The model was exercised to calculate the maximum strain energy in a critical joint due to cyclic strain, and the results were compared for a QFN with and without a heat sink. It was determined that the presence of the heat sink did contribute to higher strain energy and therefore could lead to earlier joint failure. Although the presence of the heat sink is required, careful design of the mounting should be employed to provide lateral slip, essentially decoupling the heat sink from the QFN joint strain. Details of the modeling and results, along with DIC (digital image correlation) measurements of heat sink lateral slip, are presented....

Effects of Flux and Reflow Parameters on Lead-Free Flip Chip Assembly

Jun 23, 2024 | Sandeep Tonapi, Peter Borgesen, Ph.D. K. Srihari, Ph.D

The melting temperatures of most lead-free solder alloys are somewhat higher than that of eutectic Sn/Pb solder, and many of the alloys tend to wet typical contact pads less readily. This tends to narrow down the fluxing and mass reflow process windows for assembly onto typical organic substrates and may enhance requirements on placement accuracy. Flip chip assembly here poses some unique challenges. The small dimensions provide for particular sensitivities to wetting and solder joint collapse, and underfilling does not reduce the demands on the intermetallic bond strength. Rather, the need to underfill lead to additional concerns in terms of underfill process control and reliability. Relatively little can here be learned from work on regular SMT components, BGAs or CSPs....

EFFECT OF PROCESS THERMAL HISTORY ON THE MICROSTRUCTURE OF COPPER PILLAR SnAg SOLDER JOINTS

Jun 23, 2024 | Mohammed Genanu, Jim Wilcox , Eric Cotts, Jae Joon Choi, Ki Seok Kim

Two extremes of reflow time scale for copper pillar flip chip solder joints were explored in this study. Sn-2.5Ag solder capped pillars were joined to laminate substrates using either conventional forced convection reflow or the controlled impingement of a defocused infrared laser. The laser reflow joining process was accomplished with an order of magnitude reduction in time above liquidus and a similar increase in solidification cooling rate. The brief reflow time and rapid cooling of a laser impingement reflow necessarily affects all time and temperature dependent phenomena characteristic of reflowed molten solder. These include second phase precipitate dissolution, base metal (copper) dissolution, and the extent of surface wetting. This study examines the reflow dependent microstructural aspects of flip chip Sn-Ag joints on samples of two different size scales, the first with copper pillars of 70μm diameter on 120μm pitch and the second with 23μm diameter pillars on a 40μm pitch. The length scale of Pb-free solder joints is known to affect the Sn grain solidification structure; Sn grain morphology will be noted across both reflow time and joint length scales. Sn grain morphology was further found to be dependent on the extent of surface wetting when such wetting circumvented the copper diffusion barrier layer. Microstructural analysis also will include a comparison of intermetallic structures formed; including the size and number density of second phase Ag3Sn precipitates in the joint and the morphology and thickness of the interfacial intermetallics formed on the pillar and substrate surfaces....

Component Reliability After Long Term Storage

Jun 19, 2024 | R. R. Madsen

Each year the semiconductor industry routes a significant volume of devices to recycling sites for no reliability or quality rationale beyond the fact that those devices were stored on a warehouse shelf for two years. This study identifies the key risks attributed to extended storage of devices in uncontrolled indoor environments and the risk mitigation required to permit safe shelf-life extension. Component reliability was evaluated after extended storage to assure component solderability, MSL stability and die surface integrity. Packing materials were evaluated for customer use parameters as well as structural integrity and ESD properties. Results show that current packaging material (mold compound and leadframe) is sufficiently robust to protect the active integrated circuits for many decades and permit standard reflow solder assembly beyond 15 years. Standard packing materials (bags, desiccant, and humidity cards) are robust for a 32 month storage period that can be extended by repacking with fresh materials. Packing materials designed for long term storage are effective for more than five years....

Smart Determination of Gold Content in PCBs of Waste Mobile Phones by Coupling of XRF and AAS Techniques

May 28, 2024 | Nicolò Maria Ippolito , Gianmaria Belardi , Valentina Innocenzi , Franco Medici , Loris Pietrelli and Luigi Piga

: Quantitative determination of most economic valuable metals in waste is the first fundamental operation of evaluating the feasibility of recycling processes. Field-portable X-ray fluorescence
spectrometers (FPXRFs) represent a more practical, efficient, and economic tool in determining the
elemental composition of samples with respect to conventional analytical techniques, such as atomic
absorption spectrometry (AAS) and inductively coupled plasma emission spectrometry (ICP). In
this paper, quick and smart determination of gold content in printed circuit boards (PCBs) of waste
mobile phones was studied. The aim of the research was to combine the practicality of FPXRFs
with the reliability of quantitative spectrometry analysis and evaluate the error between the two
techniques. Several samples (33) of PCBs were ground to a size below 0.5 mm, and then, the powders
were analyzed by FPXRFs at different acquisition times with five replications for each sample. The
same analyzed samples then underwent chemical attack to determine the quantitative gold content
by AAS. The obtained results were associated with FPXRFs response with the purpose of realizing
a calibration curve (100–1000 mg/kg Au). The curve was validated for accuracy and precision by
other PCBs waste samples; the control samples were added as standards to obtain a more reliable calibration curve. The curve was evaluated with RPD classification, regression linear, and Bolt–Altman
analysis.
