A good read on this app note from AVX on thermal stresses that leads to device failure on chip capacitors. Link here (PDF) Thermal shock behavior of multilayer ceramic chip capacitors was evaluated for different ceramic dielectrics with varying construction and design considerations, effects of terminations and role of physical defects to decrease the thermal […]

App note: Low temperature soldering
A study and actual test using LTS (Low Temperature Soldering) on SMT devices from Nexperia. Link here (PDF) New generation Low Temperature Solder (LTS) pastes for Surface Mount Technology (SMT) is proposed for low temperature applications such as computing. LTS pastes are commonly build on near-eutectic SnBi alloying system and therefore show reduced melting temperatures […]
A DIY SMD pick and place tool for electronics assembly
Here’s a DIY vacuum pick-up tool for SMD components: This video describes a DIY Vacuum Pick-up tool for picking and placing parts from an SMD component tape. The basic design for this tool involves using a vacuum pump and a solenoid to control the vacuum to a handpiece under control of a foot pedal. Via SDG […]
App note: Hand soldering tutorial for fine pitch QFP devices
No SMD tools removal and soldering of QFP packages tutorial from Silicon labs. Link here (PDF) This document is intended to help designers create their initial prototype systems using Silicon Lab’s TQFP and LQFP devices where surface mount assembly equipment is not readily available. This application note assumes that the reader has at least basic […]
DorkbotPDX is organizing an SMD soldering workshop
DorkbotPDX, a hackerspace in Portland, is organizing an SMD soldering workshop on the 29th of January. No tools or prior experience is necessary. For $8 you’ll get a kit to assemble in their shop. Learn how to work with surface mount technologies. This workshop is suitable for newcomers to SMT as well as more experienced […]
