Controlled reflow of flexible copper laminated polyester circuit assemblies

摘要

In a process for assembling components to flexible copper-laminated polyester circuit boards (A), high temperature-resistant adhesive tape (C) is placed around the printed circuitry in order to prevent distortion of the boards during a soldering stage. Certain components may also need to be held by retention tools which exert a force in the downward direction only (Figure 3, not shown).
