Comparing Vision‐aided Stencil Printers
T. LancasterSurface Mount Technology relies on the use of screen or stencil printers for solder paste application. Many systems now incorporate complex vision systems to provide improved…
New Reliable Methods of Measuring Temperature Distribution on Printed Boards during Operation
A. Sihlbom, H. SvärdIVF has developed two new temperature measurement methods for PC boards and microelectronic devices as a result of Swedish national research programmes. This paper presents and…
Evaluation of the Corrosion and Reliability Aspects of Printed Circuit Boards Flow Soldered Using ‘No Clean’ Fluxes
G.J. Andrews‘No clean’ fluxes (NCFs) have been in existence for a few years now. The initial claimed advantages of these fluxes were that post flow soldering cleaning would not be required…
A Modern Approach to Drill Optimisation
R. RobertsThe drilling process in the manufacture of printed circuit boards is one where there is a wide variation in the optimum parameters used by each printed circuit board manufacturer…
An Advanced Selective Metallisation Process for PTH Manufacture
J. RoubalThe Geislingen research laboratories of Dr Ing. Max Schlötter have developed Slotoposit, a new and advanced process for the manufacture of high quality PTH circuits, using…
The Effects of Ultrasonic Cleaning on Device Degradation
B.P. Richards, P. Burton, P.K. FootnerAn investigation of the use of ultrasonic agitation for cleaning printed circuit boards using CFC‐based solvents has shown that, under the standard conditions required to produce…
Rework and Repair of Printed Wiring Assemblies
E.J. FloeterAdvancements in printed wiring technology have led to an increased demand for technicians with the knowledge and manual skills necessary to perform modifications, rework or…
A Process for Multi‐level Copper‐polyimide High Density Interconnect Structures, Flex Circuits and TAB Tape
