JUKI | Reflow Soldering Ovens

Juki Automation Systems is now offering a complete line of lead-free hot-air reflow ovens from JT Automation Equipment, LTD.

Distributed with the Juki warranty and supported by their extensive and experienced service group the new line of JT ovens offer many exciting features.

Introducing the hi-tech features of JT lead-free reflow soldering ovens. JT lead-free solder reflow ovens are built in such that each main unit can be disassembled independently, reducing maintenance time by as much as fifty percent. Allowing more up time for the entire production line.

Increased thermal insulation in the chamber effectively keeps heat inside where it belongs, drastically reducing the power consumption, ultimately saving you thousands of dollars each year in wasted power.

The new-generation reflow ovens feature independent hot air circulation with flow ratio readjustment.

During the manufacture process, all machines undergo simulated strenuous load testing to ensure stable oven temperature under variable load conditions, thereby maximizing PCB end-product compliancy. The plug-and-play, modular construction reduces assembly and disassembly service time by as much as 50 percent.

The eco-friendly design not only lowers waste gas emissions, it also enhances flux recovery to reduce build-up of flux residue inside the oven.

When soldering complex PCBs, with microchips, large IC's, and even BGA's all located on the same assembly, it's particularly important to achieve the lowest delta temperature.

For higher efficient energy savings while increasing output with the same footprint area of a single oven a dual lane oven can be implemented in line with two independent placement machines, offering the flexibility expected from JUKI. Doubling the output while using approximately seventy percent of power and Nitrogen.

Aim high and embrace the future with JUKI. In the field of high-precision technology, we will be your partners on the path to mutual success.

In this video we will find out how to do reflow soldering. We need to use this technique when we are dealing with supery tiny ICs which is the case for my new project. So I will be trying out 3 different reflow soldering methods: hot air, sand and a reflow oven. At the end we will find out which method worked out and I will tell you which one was my favourite. Let's get started!

Reflow si... Reflow no! Calentando un chip

Reflow o el acto de resoldar un chip! sirve!
No lo recomiendo pero para aquellos que necesiten hacerlo y sabiendo que no es lo ideal... les dejo este vídeo!

Quiero que quede muy bien claro que no incito a la práctica de Reflow pero es verdad que mas del 80% de los técnicos no cuenta con una máquina para realizar este proceso que no solo es tener la maquina como comento en el video...
Este vídeo va para ese grupo!
La temperatura que uso como mencione en muchos videos míos... siempre utilizo mi estación al máximo y me manejo por altura... esto se logra cuando ustedes ya conocen la temperatura que maneja su estación a diferentes altura... para eso si recomiendo que en algún momento utilicen una sonda y jueguen un poco con su estación colocando a distintas alturas y midiendo lo que dice su estación con lo que usen para medir esa temperatura.
El aire cuando es para componentes comunes siempre lo uso a 1/4 d potencia y para lo que es este trabajo recomiendo a 3/4 de potencia que maneje su estación.
El tiempo usado para el Reflow es real y no fue editado, esto por si alguien le interés calcular.

El trabajo bien realizado cuando la falla es por problema de rotura de soldadura... es sin duda el Reballing pero para realizar esta técnica necesitamos contar con:
1) Una máquina que me extraiga y vuelva a soldar el chip.
2) contar con insumos de buena calidad.
3) Dominar la técnica prácticamente artesanal que es soldar de forma correcta las esferas nuevamente al chip antes de soldarlo a la placa.
Se necesita experiencia y contar con el equipamiento para garantizar un resultado duradero.
