All the technologies which are being developed to make our lives comfortable and easy bring some myths with them. Also behind every single myth attached with the technology there is a fact associated with it. Same is the case with the wave soldering technology; it too has some facts associated with it and some facts behind every myth associated with the technology.
Wave soldering technology has made the lives of the manufacturers of printed circuit board more comfortable and efficient, but still there are some facts they need to know about the wave soldering process.
Here is a description of all the myths and the facts behind them
MYTH:
The very first myth is that “Redrafting and touch-up are the part of production”.
FACT:
The fact behind this myth is that redrafting and touch-up are essential only for the reason of production failure on the assembly line. Imperfections are production failures. Redrafting and touch-up cost enormous amount of money in manual labor, ground space, redrafting stations, assessment, hand soldering tools, consumables, time management and throughput, and increases the risk of field failures. You don't have to live with your current defect rate. Don't accept it.
MYTH:
The second myth associated with the wave soldering process is that “the key to good wave soldering is thermal profiling”.
FACT:
The fact behind this fact is that Thermal profiler gives no precise information on how your board goes by through the solder waves or on your fluxer performance. Without this information your process is terminally unrestrained.
MYTH:
Third myth being “A glass plate offer all the information we need”.
FACT:
The fact behind it is that glass plates provide no precise, repeatable, enumerate or retrievable data. Neither does it calculate immersion depth. Evaluation is subjective, depending on human conclusion, eyeballing and reflex.
MYTH:
Another myth for wave soldering is that "The old wave machine is the problem" or "The new wave machine controls process."
FACT:
Some seem to be expensive machine upgrade to solve process insufficiency. The fact is that imperfection does not equal bad equipment and good equipment does not equal good process. You must control and optimize your process because no machine can.
These are some facts which should be quite helpful for the manufacturers of the printed circuit boards and slowly but surely will change the thinking of the manufacturers towards the process of wave soldering. Also these facts will make them aware of some other minorities of the process which they neglected earlier and that silly thing cost them heavily. This will bring a drastic change in the [ur=http://swpc.co.il/Page141.html]wave solder optimization[/url] process as well and will bring some very useful benefits for the manufacturers and their business. So for all the wave solder experts here is some useful stuff use it and try to make the most of it. |
