Mixed process of SMT reflow oven 

Shenzhen ETA Electronics Equipment Co., Ltd. has established long-term cooperative relations with a number of enterprises by good credit and excellent service. Here share the following three mixed process of SMT reflow oven with you:

A.Reflow one-side mixed technology:

Incoming material inspection => PCB A surface screen printing solder paste (SMT adhesive) => patch => drying (curing) => reflow soldering => Cleaning => Plugins => Wave => Cleaning => test = > Rework 

B, Reflow double-sided mixed technology:

1, incoming material inspection => PCB A screen printing solder paste => patch => dry => reflow soldering => plug-in, pin bent => flap => PCB B pasta plastic patch => patch => curing => flap => Wave => Cleaning => test => repair; A side mix ,B surface mount.

2, incoming material inspection => PCB B pastry plastic patch => patch => cure => flap => PCB A surface plug => Wave => Cleaning => test => Rework; first posted plug, suitable for SMD components rather than the case of separating element

3, incoming material inspection => PCB B pastry plastic patch => patch => cure => flap => PCB A screen printing solder paste => patch => A side reflow => Plugins => B surface wave soldering => Cleaning => test => Rework; A side mix B surface mount. First posted on both sides of SMD, reflow soldering, after the cartridge, wave soldering; A surface mount, B side mix.

4, incoming inspection => plug (pin bent) => flap => PCB PCB A side B side point plastic patch => patch => cure => flap => Wave => Cleaning => test => rework; plug-paste, apply to the separate components rather than SMD components.

C.SMT peripheral equipment process ------ reflow double-sided mixed technology

1, incoming inspection, PCB A screen printing solder paste (SMT adhesive), patch, drying (curing) A side reflow, cleaning, flap; the B-side of the PCB point plastic patch, patch curing the B plane wave soldering, cleaning, testing, repair); This process is suitable for reflow soldering, in the A side of the PCB B surface wave soldering. In the B-side of the PCB assembly SMD, SOT or SOIC below the pin (28), should adopt this technology.

2, incoming inspection, PCB A screen printing solder paste (SMT adhesive), patch, drying (curing) A side reflow, cleaning, flap; PCB B surface screen printing solder paste (SMT glue), chip, drying, reflow soldering (best only the B-side, cleaning, inspection, repair); This process is suitable for the sides of the PCB are affixed equipped with larger SMD PLCC.
