Stencil Cleaning: Consider Your BEST Options

Stencil cleaning process checklist

Did you know that certain stencil cleaners can help cut down your overall costs like labor costs, printing errors, and factory and environmental hazards? We have found that often times SMT Factory Owners and CEOs tend to overlook the costs within the stencil cleaning process that affect many factors down the operation line. It is not just the cost of the machine you are purchasing it is the overall cleaning system that you are investing in which has an effect on many different areas and should be addressed when considering your best stencil cleaning method.Here is a list of questions to consider when addressing your total investment in a Stencil Cleaning Process:
How many SMT lines are in your factory?
How many stencils are currently in use?
How do you currently clean stencils? Manually? Ultrasonic? Fully Pneumatic?
How much cleaning liquid do you use per month?
Can the process effectively clean fine and ultra fine- pitch apertures?
Does the process offer water and chemical reclamation/recycling?
Is the process fire safe? chemical safe?
Are there any health or safety hazards to consider?
What is the maintenance and potential downtime?
Does the machine consider current and future environmental regulations?
Is it cost Effective, High ROI?
Is there a built-in clean checking system?
Can the process clean dry as well as fresh paste?
Are there other objects to clean such as misprints?
What is the environmental impact?
What are the labor costs of each process?
What are the operating costs?
Is the machine fully automatic or semi-automatic? Programmable?
Does the machine free the operator from the cleaning process?
Does the machine require a specialized operator?
Does the machine require manual re-positioning?
What are the cleaning and drying times?
Does the drying process leave a film?
What size stencil does the process clean best?
Does the machine clean small stencils efficiently?
Does the machine handle large stencils?
Does the process recycle cleaning solution?
Lowers overall cleaning solution usage?
What is the electricity usage?

Overall Considerations:

Total Costs
The Environment
PCB Defects
Misprinted PCB
Solution Usage

$50000 SMT Line for LED Products Assembling



This line is designed specially for beginning manufacturers of LED lighting systems.

Special nature of LED systems production is the necessity to have high speed equipment for various LEDs and minimal set of SMD components.

The line is based on architecture of a standard line for SMD component assembly, but the equipment is modified specially for work with LEDs.


The oven length allows working with long aluminum PCBs (with high heat capacity) according to temperature profile recommended by LED vendor, without decreasing of operation time for the rest of the line.

Special vacuum nozzles are used for placing LEDs on PCBs; they are designed to avoid damage of their silicone lens. These nozzles are made of non-adhesive materials to avoid sticking of lens.

The unique ability of the line is work with LEDs in bulk; that could lower the cost of purchased components as well as the final cost of the product.

Magazine Loader and Unloader Overview

Insertion Mount machines with internal BHS can work with external devices
to automate board flow and improve throughput. This section describes how
magazine unloaders and loaders work with the IM machine Board Handling
Elevator/conveyor operation is controlled by the Advanced Magazine Loader
or Unloader.
• This device consists of an input conveyor on the bottom section, an
elevator, and an output conveyor on top. The unloader is located
upline of the insertion machine. It unloads a board from a magazine
and supplies it to the insertion machine to be processed.

Magazine loader

A magazine containing boards to be processed by the insertion
machine enters the elevator from the lower conveyor. As each
board is transferred from the topmost slot of the magazine to the
insertion machine, the elevator lifts up the magazine a programmed
distance so the next board in the magazine is in position to be
supplied to the insertion machine. When the magazine is empty, it
moves out of the elevator and onto the upper conveyor.

Magazine Loader

• This device consists of an input conveyor on the top section, an

elevator, and an output conveyor on the bottom. The loader is

located downline of the insertion machine. It receives a processed

board from the insertion machine and loads it into a magazine.

Magazine unloader

An empty magazine enters the elevator from the upper conveyor.

As each board from the insertion machine is transferred into the

bottom usable slot of the magazine, the elevator moves down the

magazine a programmed distance so the next usable slot is in

position to receive the next board. This programmable distance

allows clearance for tall components on the processed board. When

the magazine is full, it moves out of the elevator and onto the lower
