Establishing a Precision Stencil Printing Process for Miniaturized Electronics Assembly

Technical Library | 2017-06-13 13:28:22.0

The advent of miniaturized electronics for mobile phones and other portable devices has required the assembly of smaller and smaller components. Currently 01005 passives and 0.3 mm CSPs are some of the components that must be assembled to enable these portable electronic devices. It is widely accepted that about 65% of all end of the line defects occur in the stencil printing process. Given all of the above, it is critical that a precision stencil printing process be developed to support miniaturized electronic assembly.This paper is a summary of a significant amount of experimental data and process optimization techniques that were employed to establish a precision SMT printing process.

Realization of a New Concept for Power Chip Embedding

Technical Library | 2020-10-18 19:31:27.0

Embedded components technology has launched its implementation in volume products demanding high levels of miniaturization. Small modules with embedded dies and passive components on the top side are mounted in hand held devices. Smartphones have been the enablers for this new technology using the capabilities of embedded components. With this technological background another business field became interesting for embedded components – the embedded power electronics. The roadmap of the automotive industry shows a clear demand for miniaturized power electronic applications. Drivers are the regulations for the international fleet emissions which are focusing on three major trends.

Compatibility of Cleaning Agents With Nano-Coated Stencils

Technical Library | 2013-03-12 13:25:18.0

High density and miniaturized circuit assemblies challenge the solder paste printing process. The use of small components such as 0201, 01005 and μBGA devices require good paste release to prevent solder paste bridging and misalignment. When placing these miniaturized components, taller paste deposits are often required. To improve solder paste deposition, a nano-coating is applied to laser cut stencils to improve transfer efficiency. One concern is the compatibility of the nano-coating with cleaning agents used in understencil wipe and stencil cleaning. The purpose of this research is to test the chemical compatibility of common cleaning agents used in understencil wipe and stencil cleaning processes.Compatibility of Cleaning Agents With Nano-Coated Stencils

Tombstoning Of 0402 And 0201 Components: "A Study Examining The Effects Of Various Process And Design Parameters On Ultra-Small Passive Devices"

Technical Library | 2021-09-01 15:31:39.0

The long-standing trend in the electronics industry has been the miniaturization of electronic components. It is projected that this trend will continue as Original Equipment Manufacturers (OEMs) and Electronic Manufacturing Service (EMS) providers strive to reduce "real estate" on printed circuit boards. Typically, the miniaturization of components can be achieved by integration or size reduction. At present, size reduction is considered to be more cost effective and flexible than integration. Passive components, which are used in limiting current, terminating transmission lines and de-coupling switching noise, are the primary focus in size reduction due to their variety of uses.

Conquering SMT Stencil Printing Challenges with Today's Miniature Components

Technical Library | 2023-06-12 16:52:47.0

The technological advancement of component and PCB technology from through-hole to surface mount (SMT) is a major factor in the miniaturization of today's electronics. Smaller and smaller component sizes and more densely packed PCBs lead to more powerful designs in much smaller product packages. With advancement, however, comes a new set of challenges in building these smaller, more complex assemblies. This is the challenge original equipment manufacturers (OEM) and contract manufacturers (CM) face today.

Miniaturization of Cooling Solutions

Technical Library | 1999-05-06 11:52:21.0

The market's demand for increasingly powerful products, in smaller and smaller packaging, creates a cooling problem. Integrated circuit (IC) lifetime is dependent upon its operating temperature, creating a trade-off situation: either you enlarge the package to accept additional cooling, or you sacrifice IC lifetime.
