SMTnet Express: Here's What Happened On SMTnet This Week -- December 11, 2025

█ Electronics Manufacturing Technical Articles

How to Manage Material Outgassing in Reflow Oven

In a lead-free reflow process, temperatures are higher, and materials use outgasses more than in a leaded reflow process. The trends toward higher density populated boards and more pin-in-paste technology also increase solder paste use. More components and more solder paste result in more outgassing of chemistry during the reflow process. Some assemblies report condensation of ...

Reactivity Of No-Clean Flux Residues Trapped Under Bottom Terminated Components

As electronic devices increase functionality in smaller form factors, there will be limitations, obstacles and challenges to overcome. Advances in component technology can create issues that may have time delayed effects. One such effect is device failure due to soldering residues trapped under bottom terminated components. If the residues trapped under the component termination are ...

SMT Process Recommendations Defect Minimization Methods for a No-Clean SMT Process

Key competitive advantages can be obtained through the minimization of process defects and disruptions. In today's electronic manufacturing processes there are many variables to optimize. By gaining an understanding of what the defects are, and where they come from, is a key step in the process towards defect free/six sigma manufacturing. In the last decade, SMT processes ...

Controlling Voiding Mechanisms in the Reflow Soldering Process

While a significant level of voiding can be tolerated in solder joints where electrical conductivity is the main requirement, voiding at any level severely compromises thermal conductivity. For example, in LED lighting modules effective conduction of heat through the 1st level die attach to the substrate and then through the 2nd level attach to the heat sink is critical to performance so that ...

Pad Design and Process for Voiding Control at QFN Assembly

Quad Flat No Leads (QFN) package designs receive more and more attention in electronic industry recently. This package offers a number of benefits including (1) small size, such as a near die size footprint, thin profile, and light weight; (2) easy PCB trace routing due to the use of perimeter I/O pads; (3) reduced lead inductance; and (4) good thermal and electrical performance due to ...

CP45 OPT PCB files -- Is there a known way to decode *.pcb and *.opt files for the CP45FV NEO? The initial problem is that I had to edit my anc and remove some nozzles, and now I've put them back, and every new pcb I get this mismatch error, and I really don't know how to resolve this. Also, PM me or advise if there are any known Samsung techs for these old machines.
