Quality Control for Solid-State Relay

Toward's Solid State Relays Quality Management

Our factory's quality control for Solid State Relays including Opto-MOSFET Relays process is organized into the following stations: Incoming Quality Control (IQC); In-Process Quality Control (IPQC); Electronic Quality Control (EQC); Final Quality Control (FQC); and lastly, Outgoing Quality Control (OQC). All of our products go through each quality control process. This article will briefly go through each station and explain how we ensure stable quality on our relays. Now, let's walk through the QC process of our Solid State Relays and Opto-MOSFET Relays.


Incoming Quality Control (IQC)

Supervises the quality of materials before the actual production begins.
Key materials for Opto-MOSFET and Solid State Relays and their respective Incoming quality control (IQC) include:

Semiconductor Wafers

Incoming wafers go through a 100% Chip Probe Test to ensure the electrical specifications fit our needs. Afterward, our engineers apply a comprehensive visual inspection under microscopes in our cleanroom to ensure every die is perfect before continuing with the production.

QC engineers conducting standardized visual inspections on semiconductor wafers.

Lead Frames

We have developed a long-term relationship with our lead frame supplier to ensure stable quality. Our QC team inspects our supplier’s factory every quarter to ensure their environment, equipment, production standards, and capacity fits our need. After the lead frame arrives at our factory, our engineers perform a series of visual inspections to ensure proper material, shape, and reflection. Then the lead frames are scanned to confirm the dimensions fit our demand.

Gold Wires for Wire Bonding

With Gold being a precious metal, our QC engineers make sure the weight and mass of the gold fit our order. Then, the gold wires are scanned to ensure the correct dimension and radius.

Silver Epoxy for Die Attaching

We carefully control the temperature and humidity of our silver epoxy during transport. As soon as it arrives at our factory, we store them in a specialized facility to ensure the environment doesn't affect its lifespan and reliability.

LED Coating to enhance efficiency

Our LED Coating Glue is also carefully sought after during transport. Our QC team audits our supplier and makes sure they pay close attention to providing proper transporting protection; this includes controlling the temperature/ humidity and proper shock resistance embedded into the package and the transporting vehicle.

In-Process Quality Control (IPQC)

Some of our MOSFET output Solid State Relays have to meet automotive standards such as AEC-Q101; however, we make sure to exceed automotive-grade expectations throughout the die/ wire bonding and packaging of our semiconductor MOSFET Relays.
For example, we set our gold-ball-shear value 1.5 times higher than ISO standards and our wire-bond-pull value 2.3 times higher compared to ISO and IATF standards.

Solid-state relay die and wire bonding manufacturing processes exceed automotive-grade expectations.

Our QC team first simplifies the equipment operating process, then sets up an S.O.P and a comprehensive training program to fully prepare each operator to use each equipment properly; operators have to pass examinations before joining the production line. This S.O.P and training program has allowed us to lower our possibility of human error significantly; additionally, with few dozen sets of fully automated die and wire bonders along with 20 years of experience and manufacturing data, our Solid State Relays are able to reach a near-perfect defect-free-rate.

Electronic Quality control (EQC)

testers of various functions ensures our stable quality.

After our Solid State Relays are molded, they are then sent to test its electrical specifications.

Solid State Relays are tested and sorted into different color tubes.

Our software engineers write customized codes to automate electrical tests to implement different filters that sort our Solid State Relays into different color tubes. These electrical testers make a successful EQC and ensure every relay we deliver to customers meets their expectations.

FINAL QUALITY CONTROL (FQC)

After we test for electrical specifications, we then test for the breakdown voltage between input and output. First, we input 3750 V of voltage and continue for 60 seconds; for package types that require a higher breakdown voltage, we then load 6000Vs of voltage and continue for 5 seconds to make sure our Solid State Relays can withstand surge voltages.

Our functionality testers then make sure the light-emitting diode (LED) and MOSFET embedded in the relay works appropriately. Afterward, we test for customized demands such as a fast turn-on time or a lower LED drive current. These function testers are fully automated to lower human error and are all programmable for different customized demands.

OUTGOING QUALITY CONTROL (OQC)

Our packaging machine has an Automated Optical Inspection (AOI) System embedded. As it packs our Solid State Relays, it also checks for flaws on the relay, whether the size, dimensions, and marking fit the requirement (see below video for demonstration). These packaging machines serve as our outgoing quality control.

For customers that require customization, we ensure their incoming quality control requirements are also set up in our testers, by doing so, we filter our outgoing Solid State Relays once again before it is transported to our customers.

Quality Control for Reed Relays

Toward's Reed Relays Quality Management

Our factory's quality control of our Reed Relays and RF MEMS Switches process is organized into the following stations: Incoming Quality Control (IQC); In-Process Quality Control (IPQC); Electronic Quality Control (EQC); Final Quality Control (FQC); and lastly, Outgoing Quality Control (OQC).


Key materials for respective Incoming quality control (IQC) include:

Incoming Quality Control (IQC) ensures the quality of raw materials before the actual production and assembly begin.

Reed Switches

Our relationship with the switch suppliers has always been very stable; due to our large ordering volume, we are usually our reed switch suppliers' largest customer by ordering quantity. Therefore, we have the benefit to audit their factories every year and ensure their manufacturing processes fits our expectations. We also conduct a comprehensive inspection upon the switches' arrival. For example, we use a standardized Coil with a fixed resistance, and test each switch's AT value (the space in-between the two reeds), we also select switches to do life-tests to ensure their overall built quality.

Enamel Insulated Copper Wire

Insulated copper wire is an essential part of our reed relays. We require our suppliers to coat a protective layer over packages of the copper wire to ensure it stays within a specific range of temperature and humidity. After it arrives in our factory, we then do a series of pinhole detection to ensure no rusting occurs on our insulated copper wire.

Bobbin/ Lead-frame/ Solder paste

We develop long-term relationships with our suppliers to ensure stable quality. Our Incoming Quality Control Team inspects our suppliers' factory every quarter to ensure their environment, equipment, production standards, and capacity fits our need. After the lead-frames and bobbins arrive at our factory, our engineers perform a series of visual inspections to ensure proper material, shape, and reflection. Then the lead frames and bobbins are scanned to confirm the dimensions fit our demand.

In Process Quality Control (IPQC)

The manufacturing processes of Reed Relays and RF MEMS Switches are mostly automated to decrease the possibility of human error. However, our IPQC engineers set up stations in-between steps and conduct visual and machine inspection to ensure no mistakes were made in the process.

Electronic Quality control (EQC) and final quality control (FQC)

IPQC Engineers conducting comprehensive visual inspections to ensure each step goes smoothly.

The testing of reed relays in our factory applies a zero failure acceptance system. Our Reed Relay testers are able to test up to 20 different parameters. These parameters include resistance measurements throughout the relay's opening, closing and static cycles; release and operating voltage; voltage/current overdrive; input, output breakdown voltage; contact welding resistance; aging and many more.

Our factory is equipped with life-testing laboratories that can cycle relays or switches while inputting a wide range of load voltages and currents. Relays are tested up to three billion cycles.

Toward's RF laboratory is equipped with digital oscilloscopes, network analyzers, Vector Network Analyzers, Vector Signal Generators and spectrum analyzers. to test relays built for higher frequencies including our RF MEMS Switches.

FINAL QUALITY CONTROL (FQC)

After all the electrical functions are tested, we then pick out a few reed relays representing every assembly line and apply an X-ray examination. We check for the structural integrity of each relay and ensure the composition matches our standard. All the reed relays are tested for contact resistance and AT value (the measure of space in-between the two reeds). With over 25 years of data-accumulation, the equations we apply on FQC, along with statistical reasonings, can accurately locate NG products and ensure a high and stable defect-free-rate.
