High-tech kits for electronics assembly
Henkel Loctite Adhesives has a range of kits designed for the assembly of electronic components onto printed circuit boards.
Moulding compound speeds SIP integration
Hysol GR9810 is a technologically advanced epoxy moulding compound designed for system in package (SIP) on laminate applications.
Multicore LF320 requires a minimum peak reflow of only 229C, as opposed to the commonly required minimum of 240C.
This 10-degree advantage provides a comfortable safety margin when reflowing temperature-sensitive components.
As well as a print speed range of 25 to 100mm/s, LF320 offers excellent wetting on a wide range of surface finishes and has been formulated to provide high resistance to slump and solder balling.
"I think the great advantage of this material is that it provides a very wide process window, which gives us tremendous flexibility", says Vahid Goudarzi, a distinguished member of the technical staff at Motorola.
"From printing to reflow, we really stressed the material and it was able to meet our very rigorous technical requirements".
Multicore LF320 is classified as a ROMO (J-STD 004) and meets or exceeds the Bellcore GR-78-Core tests for electromigration.
The material has been optimised for reflow in air on a wide range of PCB assembly applications and reflow profiles may be extended with nitrogen.
Typical end use applications include automotive, telecommunications, consumer products and computer applications (motherboard and backplane).
Although the superior technical characteristics of LF320 are imperative to the long-term success of the material, the customer support provided for the product is equally as significant.
"In today's electronics marketplace, quality is important".
"But, I really think that excellent support is essential", says Goudarzi.
"The type of attention and service that the Henkel Electronics team provides not just for LF320, but for other materials as well is outstanding".
As the electronics industry transitions to lead-free manufacturing, material benchmarks from leading electronics manufacturers will factor greatly in the materials selection process.
Although there is no so-called "drop-in" replacement for tin-lead solder paste, Goudarzi thinks that Multicore LF320 is pretty close by Motorola's standards.
As he says: "Anybody can run it and they're going to get good results".
