What details must be considered when performing reflow soldering
In order to reduce damage to the capacitor, be sure to preheat the capacitor and the mounting substrate. Also, set the preheating conditions so the temperature difference ΔT between the solder temperature and the capacitor surface temperature is within the range shown in Table 1.
Soldering & Mounting
Radial capacitors can be hand soldered into boards using soldering irons, provided care is taken not to touch the body of the capacitor with the iron tip. Soldering should be carried out from the opposite side of the board to the radial to minimise the risk of damage to the capacitor body.

First Principles of Solder Reflow
believe you can get a good solder joint with a soldering iron: ''yes'' or ''no''? (Figure 1). The temperature of a soldering iron does not resemble the temperature required for a solder joint to form. The iron is at a much higher temperature than required for reflow of the solder joint. This large difference in temperature is

If the board is single sided, you can carry out hand soldering while preheating the chip and the board using a hotplate. The following description, which applies to a two-sided board, covers 1 the method of soldering while preheating the parts of the board and the chip to be repaired using a spot heater, and 2 the method of soldering using a spot heater alone.

6 FAQs about [Illustration of the sequence of soldering capacitors]
Should I reflow solder my film capacitors?
Vishay recommends that users observe the following guidelines for soldering our film capacitors. Adherence to these recommendations will help to safeguard product specific ations and reliability while preventi ng damage to the capacitors during soldering. Reflow soldering process should not be attempted on leaded film capacitors.
Can SMD components be used together with leaded capacitors?
When SMD components are used together with leaded ones, the film capacitors should not pass into the SMD adhesive curing oven. The leaded components should be assembled after the SMD curing step. Leaded film capacitors are not suitable for reflow soldering.
What are the conditions for manual soldering?
One recommended condition for manual soldering is that the tip of the soldering iron should be <360 °C and the soldering contact time should be no longer than 3 seconds. Even when suitable solvents are used, a reversible change of the electrical characteristics may occur in uncoated capacitors immediately after they are washed.
What temperature should a soldering iron be?
In order to ensure proper conditions for manual or selective soldering, the body temperature of the capacitor (Ts) must be ≤120 °C. One recommended condition for manual soldering is that the tip of the soldering iron should be <360 °C and the soldering contact time should be no longer than 3 seconds.
How does a solder joint work?
During the soldering process, the solder joint melts and both metal surfaces of the joint (the lead and the PC pad) are heated to the necessary temperature to bond chemically with the solder. Once the solder flows into the joint, lift the soldering iron tip straight up, so that the finished soldered joint appears cone-shaped.
