Hand Soldering, Electrical Overstress, and Electrostatic Discharge

Technical Library | 1999-05-09 13:07:16.0

This paper will give the reader a general understanding of EOS and ESD phenomena. It specifically addresses hand soldering's role in EOS and ESD and how to protect against and test for potential problems. It discusses how Metcal Systems address EOS and ESD concerns and how they differ from conventional soldering systems.

Increase Your Process Control and Lower Cost of Ownership

Technical Library | 2012-11-12 14:06:48.0

With consumers constantly looking for lower prices on their technology products and manufacturers trying to squeak out higher margins from their production lines, the need for process control and lower overhead costs have become even more important. One sector that is often overlooked is the hand soldering area of the factory. Many factories have been struggling with antiquated soldering systems for years. In some cases they are trying to make their investment in stations last much longer than they were designed for, or they are falsely trying to recoup their original investment ‐ all at the cost of higher operating expenses or even worse, reduced operator thru‐put.

Use of Pelseal® 2078 Viton® Caulk in Decapsulation of Electronics Components

Technical Library | 2019-06-18 10:18:00.0

ACI Technologies is tasked with decapsulation of electronics components for testing and investigative purposes. In the normal method of decapsulation, an analyst will drill a small indentation, with a rotary tool, in the hermetic sealant material and then apply Nitric acid to eat through the polymeric encapsulant.

Electrostatic Discharge (ESD) - Sources of Electrostatic Charges in Production Line (SMT)

Technical Library | 2010-10-13 17:29:21.0

The number of failures caused by electrostatic discharges (ESD) has been increasing for some time now. So, it is necessary for everyone, who handles electrostatic sensitive devices (ESDS), to know the reasons of such failures. This presentation will give

Oxide Thickness and Solderability Methodology to Determine Long Term Storage of BGAs and QFPs

Technical Library | 2014-10-16 16:39:12.0

Key points are: *Long-term storage of BGA & QFP products may be required due to: Fab and assembly factory transfers Product obsolescence requiring customers make lifetime/EOL purchases Providing extended service (10+ years) on vehicles Other program needs * Integrity of EOL products in terms of solderability needs to be verified.

Press Fit Technology Roadmap and Control Parameters for a High Performance Process

Technical Library | 2016-10-27 16:24:23.0

Press-fit technology is a proven and widely used and accepted interconnection method for joining electronics assemblies. Printed Circuit Board Assembly Systems and typical functional subassemblies are connected through press-fit connectors. The Press-Fit Compliant Pin is a proven interconnect termination to reliably provide electrical and mechanical connections from a Printed Circuit Board to an Electrical Connector. Electrical Connectors are then interconnected together providing board to board electrical and mechanical inter-connection. Press-Fit Compliant Pins are housed within Connectors and used on Backplanes, Mid-planes and Daughter Card Printed Circuit Board Assemblies. High reliability OEM (Original Equipment Manufacturer) computer designs continue to use press-fit connections to overcome challenges associated with soldering, rework, thermal cycles, installation and repair. This paper investigates the technical roadmap for press fit technology, putting special attention to main characteristics such, placement and insertion, inspection, repair, pin design trends, challenges and solutions. Critical process control parameters within an assembly manufacturing are highlighted.

Development of a Design & Manufacturing Environment for Reliable and Cost- Effective PCB Embedding Technology

Technical Library | 2011-10-06 13:59:04.0

The desire to have more functionality into increasingly smaller size end products has been pushing the PCB and IC Packaging industry towards High Density Interconnect (HDI) and 3D Packaging (stacked dies, embedded packaged components). Many companies in the high-end consumer electronics market place have been embedding passive chip components on inner PCB and IC Packages for a few years now. However, embedding packaged components on inner layers has remained elusive for the broader market due to lack of proper design tools and high cost of embedding components on inner layers (...) This paper will highlight several key industrialization aspects addressed in the frame of the European funded FP7 HERMES* project to build a manufacturing environment for products with embedded components. The program entered its third year and is now dealing with the manufacturing of functional demonstrators as an introduction to industrialization.

Embedded Passive Technology

Technical Library | 2014-01-09 16:40:33.0

Embedded Passive Technology is a viable technology that has been reliably used in the defense and aerospace industry for over 20 years. Embedded Passive (Resistors and Capacitors) Technology have a great potential for high frequency and high density applications. It also provides better signal performance, reduced parasitic and cross talk. This paper summarizes the selection of resistor embedded materials, evaluations of resistive material (Phase 1) and duplication of a complex digital design (Phase 2). Phase 1 –resistive materials (Foil 25Ω/sq NiCr and 1kΩ/sq CrSiO) and resistive-Ply materials (25Ω/sq and 250Ω/sq NiP) were chosen for evaluation.

SnAgCuBi and SnAgCuBiSb Solder Joint Properties Investigations

Technical Library | 2008-02-05 22:48:55.0

This study investigates the technological properties of quaternary or quinary alloys made by addition Bi or Bi and Sb elements to the SnAgCu solders. The influence of added elements on the electrical and mechanical properties of solder joints created by these solders between PCB and electronic components were evaluated.
