摘要： A technique for attaching components to PCBs involves providing a lead-free component and a PCB. The lead-free component has a package and lead-free component contacts, and the PCB has PCB contacts. The technique further involves disposing (e.g., printing) solder paste between the lead-free component contacts of the lead-free component and the PCB contacts of the PCB. The solder paste includes lead (Pb), a second metal (e.g., tin (Sn) and a third metal (e.g., Bismusth (Bi)). The technique further involves applying heat to melt the solder paste and form solder joints between the package of the lead-free component and the PCB contacts of the PCB. Such a technique is capable of concurrently mounting lead-free components as well as lead-based components to a PCB under lead-based assembly conditions (e.g., a temperature environment which does not exceed 230 degrees Celsius).

The strain detector is formed of a non-ductile material. The strain detector has a narrowed portion forming a weak link that has a characteristic of breaking when a critical strain limit is exceeded. The method of monitoring can include visual or electrical inspection. The electrical inspection can include having a strain monitoring device. The strain monitoring device has a timer connected to at least one strain detector and a memory for storing results connected to the timer. The capacitance of at least one of the strain detectors is sampled and any change in capacitance is recorded to the memory. In one embodiment, a time stamp occurs in the memory based on when an electrical property changes across at least one of the strain detectors.

摘要： A device, apparatus and printed circuit board assembly for removably coupling an electrical component with a PCB are described, which provides adequate electromechanical capability, is relatively insensitive to related heating, component removability, replacability and reworkability while minimizing wear and the possibility of resizing and damage. The device includes a sleeve for coupling with a component pin, which encloses the pin and further couples to a conductive barrel interconnecting multiple PCB layers. The sleeve conforms upon insertion within the barrel to its contour. A flange at an end of the sleeve deters over-insertion. The coupling so formed can be gas-tight.
