Delay Before Cleaning Partial Assemblies
Delay Before Cleaning Partial Assemblies
We're assembling circuit boards with a water soluble flux, but have run out of some parts. Is it acceptable to leave these partially assembled boards for 3 to 4 days, then put on the rest of the parts and then finally clean them?
Board Talk
Ask the Experts
Solution for Grape Effect
Our smaller parts are showing the 'grape' effect. What is the best solution for this since we cannot increase the conveyor speed or lower temperatures?
Ask the Experts
Cleanliness of Stencils and Misprinted Boards
Cleanliness of Stencils and Misprinted Boards
This paper covers how control of a stencil cleaner's cleaning ability is possible, but requires a preventative maintenance program.
Production Floor
Wireless Infrared Networks
Wireless Infrared Networks
Researchers have developed a wireless network based on harmless infrared rays. The capacity is more than 40 Gbit/s per ray and every device gets its own ray.
Technology Briefing
Evaluation of Molded Flip-chip BGA Packages
Evaluation of Molded Flip-chip BGA Packages
The results of this study demonstrate that the molded flip-chip BGA package is a cost effective and high reliability solution for 28nm FPGA devices.
Analysis Lab
Solderability of Vapor vs. Convection Reflow
Solderability of Vapor vs. Convection Reflow
This paper compares the solder wetting between vapor phase reflow and convection reflow using a specific Pb Free SAC solder paste.
Materials Tech
Electroplated Copper Filling of Through Holes
Electroplated Copper Filling of Through Holes
This paper discusses a through hole copper filling process for applications of high density interconnects and IC substrates.
Production Floor
Ask the Experts
Delamination Dilemma
Can you point to any other potential causes of delamination or any other steps we should take to prevent it?
Ask the Experts
Performance and Reliability Requirements of Soldering Fluxes
Performance and Reliability Requirements of Soldering Fluxes
Paper outlines the evolution of flux chemistry and details the challenges in developing flux chemistries for current and future application.
Analysis Lab
Screen Printing and Humidity
Screen Printing and Humidity
