A reflow oven or wave solder machine is capable of literally billions of alternative and conveyor speed will produce a unique profile for a processed product.
The higher melting points of the typical Pb-Free. (Sn/Ag) solders requires reflow to occur above. 240°C. The recommended soldering or reflow profile must assure
Your profile will depend upon many factors including paste chemistry, customer requirements, component limitations, oven characteristics, board layout, etc. Ultimately, quality requirements should drive the process, not adherence to these guidelines.” Lead-free Reflow Profile: Soaking type vs. Slumping type Reflow soldering is a process by which the solder paste is heated and changes to a molten state in order to connect components pins and PCB pads together permanently. There are four steps/zones to this process -- preheating, soaking, reflow and cooling. REFLOW SOLDERING PROFILE DEVELOPMENT The reflow temperature profile is defined by the relationship of temperature versus time during heating. There are two basic temperature profile types: Ramp-Soak-Spike (RSS) and Ramp-to-Spike (RTS). The RTS temperature profiles are suitable for use in most applications for enhanced solder performance.
A ramp-to-peak profile is a linear ramp to the peak (max) temperature. A soak profile displays some “plateau” within a limited How to optimize the reflow profile? Make an virtual reflow profile. Reflow the board and measure the real time thermal profile simultaneously.

In order to perform similar evaluations, check the package Reuse of reflow or any amount left-over, allocated to the risk-sharing instrument, should be made possible, under this Regulation, for the same Member State, IEC TR 60068-3-12:2014 presents two approaches for establishing a possible temperature profile for a lead-free reflow soldering process using SnAgCu solder Presents two approaches to establish a possible temperature profile for a lead-free reflow soldering process using SnAgCu solder paste. The presented process Solder profile for lead free reflow process. Solder profile for lead free reflow process. Würth Elektronik.
Generally, the thermal profile created for the reflow furnaces contains several distinct regions, namely the initial ramp, a dwell at elevated temperature, a ra.

In this way, the entire assembly sees nearly the same reflow conditions (peak temperature and time-above-liquidus) to form consistent solder bonds. Any potential thermal gradient increases as the physical size of As an initial starting point, the reflow profile shown in Figure 3 can be used with a typical range for the customer peak reflow temperature (Tp) of 235°C - 250°C.

Recommended Reflow Conditions conditions. The reflow test profile may vary with the testing instruments. The recommended reflow profile is based on the
A virtual reflow profile is based upon soldering theory, the recommended solder profile from the solder paste manufacturer, size, thickness, cooper weight, layers of the board and size, and the density of the components. CNSMT not only sale new slim kic2000 reflow oven temperature profile, but also provide repair service for all types of the profile, So if your current device has any issue while operating, and don’t want to buy a new one, then you can send to us help repair. common reflow process used today because of its low operational cost, easy and contin-uous operation, and ability to accurately control the heating and cooling profile. Convection reflow can be used in conjunction with infrared reflow and typically has multiple heating stages, so the assembly is slowly heated to the appropriate tempera-ture.
