Hi everyone, it's Adrian here from Sophist.

I've just got another quick bonus podcast episode for you

because I was having a chat with our head of new product development,

Andrew, recently about whether you should do PCB or enclosure design first and I wanted to find out what his opinion was.

Let's get into that.

Andrew, welcome back.

Hi.

Hey, Adrian.

Good to be here again.

Glad to have you on.

And the reason for getting you on this time is because we saw a conversation on the Hardware Academy forum,

and I'll leave the link to that, listeners, so you can go check it out.

It's a forum and a website that helps SMEs

and entrepreneurs to get information and support to bring their new product ideas to life and to market.

And this conversation was about whether you should do PCB design first or enclosure design first.

And actually, there was quite a lively conversation about it.

And some people thought the latter and some people thought the former.

So I was just hoping to get your feedback on this.

Where do you stand?

and also hopefully you can give us some guidance on how to make the decision on

which way to go I'm assuming of course that this is going to be most relevant to people making

electromechanical products as well yes absolutely I think this was a very good conversation between a lot of engineers in

that forum and I think that really nobody got to in any kind of a conclusion

which way is the right way well to be honest i mean enclosure

or pcb which one should it be first kind of like chicken neck situation chicken

and egg situation you know it is really really difficult to decide without knowing much about the product you know if you

are a design engineer that you just kind of settled in your own ways

and you always do the pcb design first well you may run into some problems

when you try to put that pcb in a tighter enclosure that

that the id team has already you know kind of thought of

and then you'll have to kind of go backwards

and split the pcb

or whatever else you have to do in order to fit it there uh

and the backwards just the reverse could be possible you know

if you're a closure designer and you design the enclosure that is small and nothing is going to fit in there,

then there's going to be a war in the office.

People are not going to agree with each other.

And so I think the best way, honestly, is to come up with a process

that makes it easy for everyone to understand what is the right way to do this?

What's the, you know, in my opinion, honestly, in some cases, you know,

designing the PCB first makes a lot of sense, depending on the product.

And in some cases, building the, you know, enclosure makes a lot of sense because of the fact

that size and dimensions and the ID is more important than what's inside, for example, or what the user expects, you know,

imagine if iphone was the size of a tv uh

if the iphone was the size of a tv gosh i

mean i don't think anybody would buy an iphone it would be just too big

and you know if if the enclosure was decided to be

that big uh so i'm exaggerating of course but um you know everything needs to be

down to what makes sense for that product, not only in the design office, you know, with the team,

but also with the customers that we're going to sell this product for.

If the customers demand a smaller package, then the enclosure is the one that the way that has to go, right?

You have to design it for enclosure.

But if enclosure is not so important functionality is important and you need to build a product that really functions well

then basically you you do the pcb first and and try

and fit them in a format format or fun or a package

that uh that fits just about right

so i i came up with an idea

that i think might be helpful and not necessarily written on stone steps or process.

I think it's just an idea to help at least help our young engineers to kind of find their way

which way should be.

I call it the five steps of basically,

you know, the basic design of a brand new product that that doesn't exist

as much in the industry

or in the market maybe there is one competitor is just newly uh you know uh is producing one

or you know in that kind of a scenario is what we're talking about

well the first step is creating a product requirements document what is called prd

and typically this comes from I believe product engineering team

and they kind of design the form fit

and function of the early product

and the concept product they they come up it would be

nice actually they would come up with a user manual as well and preliminary product specification

maybe a reliability requirement for example

if it needs to meet a certain for example drop height

so this PRD would have so much information there

that would help at least the design team have an idea

of what the product should be like in terms of specification this could be very useful for PCB designers.

However, step two would be an ID, industrial design for the product.

I know that a lot of us have seen on TV, you know, a guy who is designing a car from a wax.

Have you seen that?

He's like scraping a little bit more from the front,

a little bit from the back and reshaping corners and so forth.

That's basically ID.

And ID, industrial design of the product, is critical to the success of the product.

It's kind of like the fashion designer.

You know, he's trying to make the look and feel of the product be appealing at the same time, functional.

And it's really a very, very sophisticated area in the engineering.

And through this idea, it gives the engineering team,

especially young design team, a good picture in their mind

and the image of what the product is going to look like at the end

or what it should be looking like once how it should be designed

and once you have that this id document should also have a detailed

or at least rough estimate of dimensions you know length widths height

and so on and this would help the designer understand okay well

if it's going to be that big then my pcb needs to be this big roughly,

you know, so they kind of have an idea what's going on and then where the buttons should be, where the LCD should be and so on.

So all of that will be an ID design, a look and feel of the final product.

But the next, also as important, next step is product functionality.

And that would give a really important point on what's the max operating temperature,

max operating voltage and current, and how should it operate, for example, you know, if it's a telephone,

100

what kind of LCD we want, what kind of features we want on this mobile phone, for example.

101

So basically, the functionality would have all the features,

102

functionality parameters and perhaps some of the electrical specifications

103

or maybe most of the detail electrical specifications in terms of how they should be designed

104

and again you know i'm just giving you these ideas they're not written on stone

105

and every company dependent on the product they're going to do their side of how they categorize these will be different.

106

Maybe electrical specification is under functionality in one company,

107

but maybe it's under PRD or user manual in another company.

108

So there's no one cookie cut type of categorizing or writing these information.

109

But as long as you have these sections identified and discussed within Teams, I think it's going to help a lot.

110

Number four, I think, is bill of material is very important.

111

Bill of material gives the picture of what kind of components

112

and materials need to be used and how they need to be sourced, how many of those are in the, for example, in the product,

113

and whether or not the total cost estimate is within the ballpark of the funding

114

or estimate of what the project cost should be, initial cost at least.

115

So I think that bill of material is important to know something about it.

116

And then lastly, step number five is when you're designing a brand new product that perhaps maybe only one,

117

you know, competitor has it, it would be good to have a sample of the competitor for competitive analysis

118

and or maybe even re-engineering so

119

that you can design your product even 10 times better in terms of functionality or design or features.

120

Yeah.

121

And then also need to get back to your own customer if you're designing for a particular customer,

122

understand what the customer requirements are.

123

Perhaps customer wants same product in the, you know, in the field,

124

but wanted like smaller version or cheaper version or bigger version, you know, you never know.

125

So it's very important to understand what really the customer wants.

126

Maybe the customer wants an industrial version, which is more robust and reliable, right?

127

So no matter what it is, this step is important, because imagine you don't tell your team that this needs to be industrial version,

128

and they start developing your product that doesn't even meet industrial version.

129

So you, you can ship that product, right?

130

So it is an important step in terms of trying to determine, you know, what to do.

131

So in my opinion, Adrian, I think if you take these five steps to a meeting

132

and have a comprehensive meeting from heads of departments and design and development,

133

reliability, you know, purchasing, manufacturing.

134

If you have all these heads of the departments there and you're going through these, you're saying, okay, we have a brand new product that we need to design.

135

Where should we start?

136

Well, knowing these steps and knowing these information,

137

not necessarily following these steps in the manner I mentioned, it can be mixed up or it doesn't matter which one is first,

138

just having these information for each area and knowing what the product is going to look like.

139

And in engineering, sometimes we call it form and fit

140

and function of the product if you know

141

that you'll have a big idea or big picture of the product

142

and then you can easily decide and brainstorm should we start with pcb first

143

or the enclosures i think at

144

that time it will be clear do you agree yeah i do

145

and i think the point that you made about validating it as well for your potential customer is important because

146

this is all about reducing risks right you're reducing the risks of bringing out product

147

that people aren't going to want to buy you're reducing the risks of overruns in terms of time because

148

if something has to be changed that's going to be that's

149

going to take time you're reducing the risks of cost overruns as well

150

because changes certainly the closer you get to production it's It's going to be more costly.

151

So being organized and having that basis of information and those five points that you've mentioned are really, really helpful for that will help you to choose the right thing at the right time.

152

So you don't want to end up making an enclosure, going through all of the time and expense to design it, start producing it, and then it's too small, for example.

153

Right, right.

154

Exactly.

155

I mean, if you imagine if you start with enclosure and too small, well, for sure, those PCBs are not fitting there.

156

And then on the other hand, if the enclosure is supposed to be small, then there should be a good communication with the PCB team

157

that the typical way of designing the PCB is not going to work.

158

It's just we need to come up with a ways of really small, maybe flex cables instead of, you know, if the product is small, like a digital watch, for example.

159

so so there are other ways that other technologies

160

that they're more miniature you're the many layers to each one of these pcbs

161

so there are ways of doing these things

162

but you just have to i think the rule number one

163

is communication among teams between cross-functional teams you definitely have to have very good communication

164

and i think that project managers

165

and the product engineers who are trying to launch this brand new product they need to be a good communicator

166

but also really need to manage the teams in a way that they understand that you know if the prod

167

enclosure needs to be go uh designed first then let's go with that let's not stick to

168

what you learned in another company uh necessarily uh maybe brainstorm and come up with

169

an innovative new process yeah great that's uh that's very very helpful

170

and hopefully that puts people's minds at rest if if they're wondering well pcb first or enclosure first but i suppose

171

in a nutshell it depends it does excellent guidance there andrew thanks for popping by
