HASL and HASL lead free difference in PCBA manufacturer

Now there are two kinds of processing technology of electronic processing plants, according to customer demand for choice, has a lead-free processing technology and processing technology have lead. There are a lot of customers don't know the difference between the two, in fact, only know lead-free processing more expensive, process cheaper lead, lead-free solder is not used in the process of 100% does not contain lead, only compared with leaded solder lead lower element. Below small make up more experience, both in the comparison, specific to solve the difference between them. 1, the cost is in the process of lead-free, because of the characteristics of the solder itself need some welding auxiliary material, and used in the reflow lead-free makes that the cost of using leaded solder paste increased 2 times, at the same time also need to use in the process of wave soldering tin tin line article also increased at least 2 times the processing cost, thus is lead-free processing costs are higher; 2, used in the manufacturing process of being lead-free lead-free solder temperature is 217 ℃, melting point and melting point of lead solder temperature is 183 ℃, because of the low melting point of lead solder, less heat damage to electronic components, processing after the completion of the solder joints are more light, intensity is also more rigid, quality is better; 3, reliability have lead solder containing lead has great harm to human body, long-term exposure to have great influence on human health. Now widely used in the international market, meanwhile, lead-free process, also is a kind of protection of the environment, after all, people have realized the increasingly serious environmental pollution harm to them. Related pcb factory in the process of electronic assembly or PCBA processing, can choose according to the above process, not the pursuit of veto lead-free technology and has the advantage of lead process.
