Coating does not always prevent failures; it is just as important to look at your cleanliness levels just as you would with an assembly that is not bound for coating. If you have a dirty assembly, you might be buying a little time, but ultimately, you've sealed your own fate.
Before parts are added, a typical printed circuit board (PCB) has four ingredients: substrate, metal, solder mask, and silkscreen. Each of those four ingredients comes in a host of variations, and each has varying degrees of “requirededness.”
Protecting bare dies on a PCB or substrate is a major process of microelectronics assembly. As we’ve said before, microelectronics assembly and manufacturing work in tandem with traditional SMT manufacturing for complete PCB...
Your Lean Six Sigma program needs to be rightly sized to your organization’s structure for it to be sustainable. The second phase involves establishing the six pillars of operational effectiveness. Attaining quality systems...
If you’ve been in the SMT industry for any length of time and involved in ordering stencils, you may have instructed your stencil supplier to design your stencil to "industry standards" or per IPC standards. These are...
