SHENMAO America today announced plans to exhibit at the eSMART Factory Conference, jointly organized by Global SMT & Packaging magazine and the SMTA, on Thursday, May 24, 2018 at the Plug ‘n Play Tech Center in Sunnyvale, CA. SHENMAO will highlight the new PF606-P245 Lead-free Zero Halogen Solder Paste. PF606-P245 paste improves ICT testability by completely removing flux to prevent contamination of test pins during test operation.

Although reflow ovens may not have been dramatically changed during the last decade the reflow process changes step by step. With the introduction of lead-free soldering not only operation temperatures increased, but also the chemistry of the solder paste was modified to meet the higher thermal requirements. Miniaturization is a second factor that impacts the reflow process. The density on the assembly is increasing where solder paste deposit volumes decreases due to smaller pad and component dimensions. Pick and place machines can handle more components and to meet this high through put some SMD lines are equipped with dual lane conveyors, doubling solder paste consumption. With the introduction of pin in paste to solder through hole components contamination of the oven increased due to dripping of the paste.

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 vapors when the cold printed circuit board enters the oven. Little is known about the interaction between these condensed materials in terms of the interaction between these condensed materials and the reliability of the assembly. Apart from the question of reliability, a printed circuit board contaminated with a small film of residues after reflow soldering is not desirable.

. Be careful on coax cable with Teflon dielectrics in the cable, as if that gets too hot during the soldering of the center contact, it will expand and may impact the ability to solder the connector
