Topic : Reflow Oven

 

So far, I’ve been selling plenty number of reflow ovens in my territory! Most of the SMT clients will pay more and high attention and concentration on chip shooters, for the sake of making great profit to their production, directly.

 

However, in an assembly line of SMT, processes of reflowing and printing play important roles in a production as well. Both processes have critical role on lower PPM NG.

 

Collective information below is being presented after I have been active so many

year in SMT industry, based on my real experiences and clients’ feedbacks!

 

How to select a good oven for your SMT line?

 

There are many types of ovens existing in Malaysia market, but what’s the best oven suits this region? Herein are some basic tips been mostly required.

 

Basic Requirement

Reason

Temperature Profile and ∆T

How good the ∆T for High mixed components PCB?

Easy Maintenance

How long it can be last without any maintenance?

Reliability of Parts

Life span for heater, blower fan, conveyor chain, conveyor rail and etc.?

Small Foot Print

Factory spacing?

Service after Sales

How fast the supplier is able to response and solve when problem occurs?

Low power of Consumption

Power saving = Reduce CO2

Environment Friendly

Power saving, less heat wasting and good isolation

Competitive Pricing

As cheap as possible
