Why SMT Reflow Soldering Oven Cannot Be Avoided By Electronic Assembling Firms Why SMT Reflow Soldering Oven Cannot Be Avoided By Electronic Assembling Firms January 20 Darrelle Revis Jersey , 2014 | Author: Harriett Crosby | Posted in Marketing
When it comes to soldering of electrical components on to printed circuit board (PCB), surface mount technology (SMT) is the most widely used method. The SMT reflow soldering oven is the machine that has greatly contributed to this technology. Highly technical principles in bonding are all put together to ensure optimal functionality of this particular machine that has literally transformed the electronics industry. In addition to precise control of this process, the machine consumes less power than other methods used and produces more products per unit time than any other method.


This is one of the machines that get used more often than any other machines in the electrical line of assembly. Before passing over to the oven, the solder paste made of flux, small solder particles and chemical cleaning agents is used to loosely attach the electrical components on to the printed circuit board (PCB) and then sent to the next step.


It involves joining of electrical components on to contact pads with solder paste and heat. In the process of highly controlled heating that take place in the oven, solder melts in the right position and permanently join the electrical components on PCB in the process.


SMT soldering ovens are designed with specific zones, stages which numbers to a total of four. It all starts from the preheat zone. In this stage, the melting temperature of the solvent in paste is set. The timetemperature relationship also known as ramp is determined to help control heating in other zones.


At thermal soak zone, the components are exposed to heat for about 60-120 seconds. The heat produced at this stage should be enough to remove all the volatiles of solder paste. The reflow zone then takes over. At this stage, the components get exposed to the maximum possible temperature which is normally set a few degrees below the maximum temperature tolerable by the component with the lowest tolerable temperature. This reduces surface tension at joints, the result of which is the bonding between pads and the electronic components.


In the fourth and final zone Brandon Marshall Jersey , the process of cooling takes place. This too is a controlled process. The heating and cooling is such controlled that the PCB and components are not exposed to thermal shock. This is perhaps what makes SMT reflow soldering oven outperform all other methods of bonding.


The heaters in these types of oven are made of ceramic materials with various options through which heat reaches the heating zones. The heat transfer can either be through hot air (radiation) and infrared electromagnetic radiation among other alternatives.


SMT reflow soldering oven comes with a number of advantages such as simpler and much faster automated assemblies, very small levels of errors in component mounting, high level of production rate (some capable of placing up to 136,000 components per hour), possible to mount components on both side of the PCB, and electrical efficiency.


Electronic assembly just like any other industry is highly competitive. In order to remain a relevant market player, a firm must acquire the latest technology and most efficient production methods. The use of SMT reflow soldering oven is no longer optional in electrical assembly. In addition to higher level of production, efficiency and lower power consumption, the machine guarantees firms future survival and profitability.

RA Dickey Wins 20th Game - RealGM Wiretap

Mets knuckleballer R.A. Dickey is the first 20-game winner on a sub-.500 team since Roger Clemens with the Blue Jays in 1997 and a legitimate NL Cy Young Award contender.


Dickey limited the Pirates to three runs in 7 23 innings Thursday before departing with a three-run cushion. The Mets held on for a 6-5 win as Dickey improved to 20-6.


"It was as hard as it's ever been to not get emotional, that's for sure," Dickey said. "I mean New York Jets Hats , from the get-go, from the introductions to the last pitch."

Public Relations Business Assists in Making popular an Organization Englemann Sawer
Submitted 2014-04-01 15:10:26 Business image and reputation is a product with the quality of interactions that a business offers with its stakeholders Public relations firms are firms outsourced with regard to communicating as well as establishing a powerful bond with all the stakeholders of an enterprise. Some of the areas that these firms handle include press relations, customer relations, trader relations, public affairs, business communication and also internal conversation. While some organizations may opt for an in-house group to manage their particular interactions with all the current business gamers, the strategy is prone to limitations of time and experience. The ultimate choice for a company is to outsource the role to be able to public relations firms that provide numerous benefits.

1. Strongly industry the business
Public relations firms issue themselves with creating a positive and great business image. They push all their endeavours towards the good results of the objective as they appreciate the value of a strong business picture. Shortly put, a good image sells. Public relations firms form up marketing and sales communications between the business and its clients. Customers are the .
