Medical Electronic Assembly And Soldering In Ferrisburg Vermont

By Janet Powell


When two metals are joined together by either use of solder (filter metal) or by melting is called soldering. Normally the adjoining metal has a higher melting point than the solder. Almost every filter metal is made of lead but due to health and environmental risks, it is always advisable to use alloys which are lead free for both plumbing and electronic purposes. When carrying out the process of assembly and soldering in Ferrisburg Vermont the following factors must be considered.

One of the factors to consider is the Resin temperatures. Before potting process commences, the resin must be heated up in order to allow better flow of potting mixture through the system once production begins. Resin exists in different varieties and due to this fact it is always recommended to enquire from the supplier the optimal temperatures which the material should be heated.

As technology advancements are being done in the industry, more and more reduced size of hand held devices are being produced. This has been made possible by use of filter metals which are lead free. Also mass production can be achieved when the pitches are tight which leads to board free problems.

Potting method can be carried out in two ways. One of the methods is by use of a piston machine which has hardener and resins cylinders which are sized. The correct portions are pushed to the mixing area once the pistons are inserted inside the cylinders.

Another challenge faced in gathering of these devices is that through-hole components with surface mount technology (SMT) must exist. This is very challenging since SMT cannot totally replace through-hole technology. Components which have been manufactured using through-hole technology are on high demand in the medical field. Some of these components may include resistors, connectors, digital display and capacitors. Due to the design nature and power requirements the technology still remains the best in manufacture of these devices.

For soldering process to be carried out the solder must be heated up. Studies have shown that lead requires less temperatures compared to the lead free solder. High temperatures are associated with board war page and pop corning problems.

The force at which these materials are mixed should also be considered. To obtain a homogenous mixture, pressure has to be applied. In cases where low pressure is used the resulting mixture is always uneven. Its always advisable to contact the supply on the exact pressure to be applied.

The dispensing volume should be considered. This is achieved by carrying out a single controlled shot or multiple shots. The number of shots to be carried out depends on the electronic assembly size to be potted. When carrying out the process, the dispersion speed of the mixture should always be the same rate at which one is able to cope with the assembly line in a controlled way. Also it is advisable to carry out the process in a ventilated room.
