Selective Soldering Technologies

• Thanks to the growing popularity of SMT
  technology, the new through-hole technology is
  taking up much less real estate on a PCB
  assembly.
• However, the through-hole pins are still a
  necessary for many boards, and for that they
  still need to be soldered.
• Since this process can cause some serious
  distress for the production managers, a number of
  manufacturers have opted for selective soldering
  technology as a precise and cost effective way to
  solder through-hole technology.

Why are People Considering Selective Soldering
Method?

• Its a fact that before the advent of reflow
  soldering, boards that used to have a high number
  of through-hole pins usually underwent wave
  soldering.
• This is a process where a board passes through a
  solder wave. However, in case of through-hole
  technology, this posed few problems as the pins
  could withstand more thermal shock and were much
  less expensive.
• But on the other hand the SMT packages are more
  sensitive and expensive and must be soldered in a
  reflow oven.
• Since through-hole pins cannot be soldered in a
  reflow oven but needs to be soldered separately,
  manufactures opted for doing it by hand or
  through a selective soldering machine.

Advantages Of Selective Soldering Technologies

• One of the biggest quality of selective soldering
  is that in spite of the face that market is now
  demanding for smaller wired components, its
  still the most efficient and cost-effective
  method. This method approaches each solder joint
  individually and thereby match the individual
  soldering parameters.
• Another fact is that one can use individual
  product-specific mini dip soldering nozzles which
  helps to solder several pins or components
  simultaneously to achieve short cycle times.
  Selective soldering methods are economically
  successful in the processes are adapted exactly
  to the applications and quantities.

Challenges You Might Face With Selective
Soldering

• In spite of being one of the most convenient
  methods, like any other soldering processes,
  selective soldering also has its own set of
  challenges. Lets look at them below.

• Since Selective soldering method applies heat to
  only one place on the board, the present in the
  solder paste might not activate properly, which
  might lead to the residue to spread to other
  parts of the board, creating a complete mess.
• There is another way which can help you prevent
  the contamination. And that can be achieved by
  implying or updating existing contamination
  testers. Another proven method for catching flux
  migration can be ionic testing which is also used
  to measure the potentially harmful board
  conductivity.
