Excessive Reflow Temp. Excessive Heating Rate. SMT Reflow Soldering Profile of Reference Typical SMT Reflow Profile Thermal profile done 2 times on each part tested; Thermal profile in accordance with CEI 60068-2-58 / EN 60068-2-58; Pre-heat to a maximum of 200°C for 30 seconds; Reflow at a maximum of 245°C for 10 seconds; Maximum time above 183°C for 60 seconds There are two different profiles involved in the reflow process – soaking type and slumping type. The Soaking type is similar to a trapezoidal shape while the slumping type has a delta shape. If the board is simple and there are no complex components such BGAs or big components on the board, the slumping type profile will be the better choice. Reflow – Explained With Procedure. Reflow soldering is the most common process used by manufacturers and repair shop to mount electronic components on a printed board circuits and reflow is the stage of “reflowing solder” where the solder or solder paste changes its state from solid to liquid at the high heat temperature to make solder joint on PCB (printed board circuits).

It supports the following applications that are related to convective reflow soldering of electronic assemblies: Offline reflow profile optimization for a specific PBA and reflow oven, based on a single reflow profile measurement. Find soldering techniques for Semtech's various package types with our reflow profiles. Click here to find your package type. High quality quick turn PCB Services https://www.pcbway.com In this video I will take you through the process of creating custom reflow profiles on the T-962 Types of Reflow Profile: Ramp to Spike graph (RTS): 1)It is a linear graph. Starting at start of segment and ending at peak temperature, the soak period is part of ramp.

Reflow the board and measure the real time thermal profile simultaneously. Check the solder joint quality, PCB and component status. Burn-in a test board with thermal shock and mechanical shock to check the board’s reliability.

The reflow profile shown below was used by us to evaluate the heat resistance of the package. In order to perform similar evaluations, check the package

For all soldering methods, the optimal reflow profile for a circuit board assembly is dependent on the solder material, solder amount, flux, temperature limit of each soldered component, heat transfer characteristics of the circuit board and component materials, and the layout of all components.

A properly designed and adjusted reflow profile is one of the most important factors to achieve defect-free, high quality solder joints during a surface mount 

If the board is simple and there are no complex components such BGAs or big components on the board, the slumping type profile will be the better choice.

profile for the specific solder being used. The manufacturer’s profile or the typical solder reflow profiles table in this document can be used as a starting point for profiling the process. Caution: Please contact your solder paste manufacturer for exact solder profile requirements. When using thermocouples for profiling, it should be noted that
